From e732380fb58668b393e3461343f35a9db60ae365 Mon Sep 17 00:00:00 2001 From: Emperiusm Date: Fri, 17 Apr 2026 12:49:23 -0400 Subject: [PATCH] feat(scanner): detect documented vulnerability classes on known-vulnerable apps MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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/-{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 \` 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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --- .../src/opentools/scanner/known_vuln_apps.py | 237 ++++++++++++++++++ .../scanner/profiles/app_server.yaml | 9 +- .../scanner/profiles/redis_audit.yaml | 28 +++ .../opentools/scanner/profiles/web_quick.yaml | 10 +- .../cli/src/opentools/scanner/scan_cli.py | 39 ++- 5 files changed, 316 insertions(+), 7 deletions(-) create mode 100644 packages/cli/src/opentools/scanner/known_vuln_apps.py create mode 100644 packages/cli/src/opentools/scanner/profiles/redis_audit.yaml diff --git a/packages/cli/src/opentools/scanner/known_vuln_apps.py b/packages/cli/src/opentools/scanner/known_vuln_apps.py new file mode 100644 index 0000000..2e55d58 --- /dev/null +++ b/packages/cli/src/opentools/scanner/known_vuln_apps.py @@ -0,0 +1,237 @@ +"""Expand detections of known-vulnerable-by-design applications. + +Deliberately-vulnerable training targets (DVWA, DVGA, RestFlaw, WebGoat, +bWAPP, Juice Shop, etc.) advertise their vulnerability classes as part of +their purpose.
