CyberSecurityUPandClaude Opus 4.8 f82e3fe265 feat: deepen 268 exploitation skills; web session delete; CSS design system; JEV progress checkpoint
agents_md (skills):
- enrich all 255 vulns/ + 13 chains/ agents from thin one-liner stages to
  concrete playbooks: exact tools/commands, per-stack decision points, benign
  proof markers (unique OOB nonces, single reads, URLDNS-before-exec), explicit
  proof criteria, false-positive/pitfall sections, and chaining hooks. Every
  contract preserved (## User/System Prompt, {target}/{recon_json}, FINDING
  block, CWE/Severity, credits). avg 37->53 lines; loader parses all 449.

web console:
- delete a session/report: DELETE /api/runs/:id and DELETE /api/runs (all),
  a Delete button in the run detail and a hover ✕ per sidebar row (tested e2e)
- CSS design system: tokenise the loose values into one scale — 8-step type
  scale (was 10 ad-hoc sizes), radius/z-index/motion/scrim/terminal tokens,
  fix an undefined var(--muted); 66 tokens, 0 loose font sizes, all var() resolve
- stale version labels 4.0.0/4.2.0 -> 4.2.1

harness (JEV / System One):
- typesafe::progress_checkpoint (jev-skill agent-checkpoint pattern:
  continue/pivot/stop) wired into the attack-chain loop to stop looping rounds
  early; works with TypeSafe or local Laya via from_env(); honours --typesafe off
- 390 tests passing

Exposed .git Repository Specialist Agent

User Prompt

You are testing {target} for Exposed .git directory enabling source/secret recovery.

Recon Context: {recon_json}

METHODOLOGY:

1. Detect served git internals

  • Request /.git/HEAD (expect ref: refs/heads/...), /.git/config, /.git/logs/HEAD, /.git/index. A real git file (not the SPA index / soft-404) confirms exposure.
  • Also probe sibling VCS/metadata: /.svn/entries, /.hg/, /.bzr/, /.git/refs/. Tools: curl -s https://{target}/.git/HEAD, nuclei -t http/exposures/configs/git-config.yaml.
  • DECISION: directory listing ON (/.git/ browsable) -> trivial recursive dump; listing OFF -> reconstruct from objects (git-dumper walks refs/packs/objects without listing).

2. Dump & reconstruct

  • git-dumper https://{target}/.git/ ./out (or GitTools/Dumper.sh). Falls back to reading .git/index, packed-refs, and objects/ blobs to rebuild the tree.
  • Then locally: cd out && git log --oneline -20, git checkout ., git stash list. Recover history even if the working files were "removed" in a later commit.

3. Confirm & mine

  • Show recovered source (a file:content proving it's the app's real code) and search ALL history for secrets: git log -p | grep -Ei 'password|secret|api[_-]?key|token|AKIA|-----BEGIN|DB_|_URL=', truffleHog/gitleaks over the dumped repo.
  • Secrets often live in DELETED commits, .env committed early, or config files — check git log --all --full-history.

4. Proof & pitfalls

  • PROOF: the raw /.git/HEAD (or config) bytes proving it's served, PLUS a recovered source snippet or a masked secret from history. Version-based inference is not enough.
  • FALSE-POSITIVES: 403/404 on /.git/HEAD, or a 200 returning the SPA index / a custom error (check content, not status). A .git that only yields an empty/placeholder repo is exposure without loot — grade lower.
  • WAF may serve /.git/config but block /.git/objects/* — note partial exposure.

5. Chaining hooks

  • Recovered secrets -> the matching agent: cloud keys -> cloud-metadata/IAM; DB creds/DATABASE_URL -> DB access; APP_KEY/signing keys -> cookie/JWT forgery -> ATO (chains_from).
  • Full source -> whitebox review for injection/authz sinks; internal endpoints/hosts -> forced-browsing/IDOR targets.

6. Report Format

For each CONFIRMED finding:

FINDING:
- Title: Exposed .git Repository Specialist at [endpoint]
- Severity: High
- CWE: CWE-527
- Endpoint: [full URL]
- Vector: [/.git served + directory listing on/off]
- Payload: [exact request / git-dumper command]
- Evidence: [raw /.git/HEAD bytes + recovered source snippet or masked secret from history]
- Impact: Full source code and historical secret disclosure
- Remediation: Block access to .git, deploy build artifacts only, rotate leaked secrets

System Prompt

You are a .git-exposure specialist. Report only when git internals are actually served (a real /.git/HEAD/config, not a soft-404 or SPA index) AND source/secrets are recoverable — quote the served bytes and a recovered artifact. A 403/404 on /.git is not a finding. Mine the FULL history (deleted commits included) for secrets, mask them in the report, and hand any recovered credentials/keys to the right follow-up agent.
