Moved entrypoint.sh copy target from /app/entrypoint.sh to
/entrypoint.sh in the dev Dockerfile. The dev compose bind mount
./backend:/app overlays /app entirely; placing the entrypoint above
that boundary ensures the image-baked script is never shadowed by
host directory contents. No startup failure was reproduced — this
is a preventive hardening change.
urllib.parse.quote(path, safe='/?&=') was re-encoding % to %25 in
already-encoded attack paths (XXE, XSS, traversal payloads). Replaced
with a manual first-? split: path component encoded with safe='/%\'
(preserving existing percent sequences and backslash traversal vectors),
query string passed through untouched. Covers all 53 attack payloads
across 7 simulation modes. Inline comments removed from XXE_PAYLOADS
to match the style of all other payload lists.
The final branch of _XXE_INJECTION was missing % separators between
hex pairs. Pattern %(?:25)?53(?:25)?59... never matched because after
consuming %53 the next sub-pattern expected 5 or 2, not %. Fixed by
inserting % anchors between each pair so both single-encoded
(%53%59%53%54%45%4D) and double-encoded (%2553%2559...) SYSTEM strings
match correctly. All existing XXE branches are unaffected.
- add 1200x630 og-image.jpg plus Open Graph and Twitter Card meta tags so
the live demo renders a rich preview when shared (LinkedIn, etc.)
- omit og:url to avoid crawler cache canonicalizing share URLs back to a
stale entry
- justfile: add redeploy recipe (tunnel down, cached build, up -d with the
backend profile and remove-orphans); strip the exported dev .env overrides
so it deploys under the prod project name and ports
- install.sh: clearer live-capture hint (setcap, then run without sudo)
Add a --report flag to the pcap command that prints one forensic summary of
a whole capture (endpoint inventory, fingerprint distribution, intel verdicts,
detection alerts, and a coverage section with the TLS miss rate and throughput)
instead of the per-event stream, folding in intel and detection automatically
when a seeded database is present. Add a tls_handshakes_fingerprinted counter
and Counters::tls_miss_rate so truncated and multi-segment ClientHellos the
capture clipped are reported rather than mistaken for absence. Add criterion
benches over the vendored captures and the parse/hash hot path. Plus frontend
landing and asset polish.
materializeDefaults now sets CKA_ENCRYPT/DECRYPT/SIGN/VERIFY/SIGN_RECOVER/VERIFY_RECOVER/WRAP/UNWRAP/DERIVE (plus ALWAYS_AUTHENTICATE for private keys) to CK_FALSE when absent, per CKO_PUBLIC_KEY/PRIVATE_KEY/SECRET_KEY; smoke sets the RSA wrap and recover usage flags.
Passive TLS client and server fingerprinting from packet captures. Two-crate
workspace: tlsfp-core (parsing and fingerprint logic, no I/O, unsafe forbidden)
and tlsfp (clap CLI). Edition 2024, MSRV 1.85.
Core (M0-M4): a hand-rolled bounds-checked TLS parser for ClientHello,
ServerHello, and the TLS 1.2 Certificate chain, plus the full fingerprint
family computed byte-exact against published vectors: JA3/JA3S (MD5), JA4/JA4_r,
JA4S, JA4H, JA4X, and JA4T. GREASE is stripped, wire order and unknown cipher
and extension values are preserved.
Pipeline (M5): a pcap and pcapng file reader behind a PacketSource trait,
etherparse L2-L4 decode (Ethernet, raw IP, BSD loopback, Linux SLL and SLL2,
VLAN and QinQ), and a hand-rolled per-flow TCP reassembler with wrapping serial
arithmetic, out-of-order parking, first-write-wins overlap resolution, and
bounded memory. The tlsfp pcap subcommand fingerprints every handshake in a
capture, as readable lines or NDJSON.
Verified three ways: 94 tests including unit KATs, nine real-pcap full-pipeline
KATs against the FoxIO sample corpus, and property tests that reassemble
arbitrarily segmented and reordered streams. Builds clean on stable and MSRV
1.85; clippy -D warnings and rustfmt clean.
Test captures under testdata/pcap are vendored unmodified from the FoxIO ja4
repository with per-file SHA-256 provenance.
