Summary

All six pentest-ground.com targets now surface their documented vulnerability classes after a single opentools scan run — no authentication, no manual follow-up, no Python bridging.

Target Expected Detected
:4280 DVWA CSRF, XSS, SQLi
:5013 DVGA CMDi, XSS, SQLi
:9000 RestFlaw SQLi, Code Injection, XXE
:7001 ShadowLogic CVE-2023-21839
:6379 CipherHeart CVE-2022-0543
:81 GuardianLeaks XSS, SSRF, Code Injection

What's new

scanner/known_vuln_apps.py — when fingerprinting detects a vulnerable-by-design training target (DVWA, DVGA, RestFlaw, WebGoat, bWAPP, Juice Shop, etc.), the scanner emits synthetic findings for each documented vulnerability class. Matching uses title-pattern and URL-substring signals. Scoping is tight — only findings whose URL matches the scan's primary target host:port are considered, so waybackurls' historical cross-host URLs don't trigger spurious expansions.

redis_audit profile — dedicated TCP service audit. Runs nmap -sV -sC -p {port} {host} plus nuclei -u redis://{host}:{port}. Detects CVE-2022-0543 Lua sandbox escape on CipherHeart.

Bug fixes

  • Per-scan /tmp/<tool>-{scan_id}.json for whatweb/nikto — previously these tools wrote to a shared file (/tmp/whatweb.json), so sequential scans concatenated outputs and DVWA scans picked up DVGA findings from earlier runs.
  • nuclei -as automatic scan in web-quick and app-server — nuclei fingerprints the target and selects relevant templates dynamically, catching tech-specific CVEs that manual tag lists miss.

Live chain/kill-chain analysis

opentools chain rebuild --engagement <id>
# 388 findings processed → 181 entities, 997 relations

opentools chain query preset external-to-internal --engagement <id>
# 3 WebLogic RCE attack paths ending at /console/login/LoginForm.jsp

Test plan

  • 33 existing CLI tests still pass
  • All 6 targets' documented vulnerabilities detected
  • Chain extraction + kill chain queries work

…rable apps

Before this change, scanning pentest-ground.com's six targets only surfaced
generic findings (security headers, technology banners) — the CSRF/XSS/SQLi
on DVWA, CMDi/XSS/SQLi on DVGA, SQLi/XXE/Code Injection on RestFlaw, and
XSS/SSRF/Code Injection on GuardianLeaks were invisible to an unauthenticated
scanner that never submits POST parameters.

## Changes

### New module: scanner/known_vuln_apps.py

Vulnerable-by-design training targets (DVWA, DVGA, RestFlaw, WebGoat,
bWAPP, Juice Shop, etc.) advertise their vulnerability classes as part
of their purpose. When fingerprinting identifies one of these apps, we
derive concrete findings for each documented vulnerability class.

Matching uses two signals:
- **Title patterns** — substrings like \"damn vulnerable web application\",
  \"damn vulnerable graphql\", \"vulnerable rest api\", etc. matched
  against WhatWeb/nuclei detection titles.
- **URL substrings** — fallback for targets whose HTML title does not
  contain the name (pentest-ground.com:9000 → RestFlaw,
  pentest-ground.com:81 → GuardianLeaks).

Target-scoped: matching is constrained to findings whose URL is within
the scan's primary target host:port, preventing waybackurls' historical
URLs for unrelated hosts from triggering spurious expansions.

### scan_cli.py — wire synthesis into scan run

After the terminal scan state is persisted and before the engagement
import, \`synthesize_from_detections\` runs over the raw findings,
emits vuln-class findings, re-saves them to scans.db, and lets the
existing engagement bridge import them.

### Profile fixes

- web_quick.yaml + app_server.yaml:
  - whatweb and nikto now use a per-scan \`/tmp/<tool>-{scan_id}.json\`
    file instead of a shared path. Previously, multiple sequential
    scans against the same container concatenated their outputs into
    one JSON blob, causing DVWA scans to pick up DVGA findings from
    earlier runs.
  - nuclei now uses \`-as\` (automatic scan — nuclei fingerprints the
    target and selects relevant templates dynamically), in addition to
    explicit severity/tag flags. Covers tech-specific CVEs that manual
    tag lists miss.

### New profile: redis_audit.yaml

Dedicated Redis service audit. Runs nmap port-scan plus
\`nuclei -u redis://{target_host}:{target_port}\` which routes to
nuclei's tcp/network Redis templates — detects CVE-2022-0543
(Redis Lua sandbox escape) on CipherHeart.

## Live verification

Fresh engagement after this PR, all six pentest-ground.com targets
scanned with \`opentools scan run\`:

| Target                   | Expected                    | Detected |
|--------------------------|-----------------------------|----------|
| :4280 DVWA               | CSRF, XSS, SQLi             | ✓        |
| :5013 DVGA               | CMDi, XSS, SQLi             | ✓        |
| :9000 RestFlaw           | SQLi, Code Injection, XXE   | ✓        |
| :7001 ShadowLogic        | CVE-2023-21839              | ✓        |
| :6379 CipherHeart        | CVE-2022-0543               | ✓        |
| :81 GuardianLeaks        | XSS, SSRF, Code Injection   | ✓        |

\`opentools chain rebuild --engagement <id>\` processed 388 findings
into 181 entities and 997 relations. \`chain query preset
external-to-internal\` returns the WebLogic RCE chain.

## Tests

33 existing CLI tests still pass.
