metasploit-cursor-harness: Skill for Cursor

.cursor/skills/web-app-pentest/SKILL.md

web-app-pentest is a skill for Cursor from Suzu-Testing/metasploit-cursor-harness. It costs 53 tokens per session (2,211 once invoked), scanned A, original, MIT.

A guide for testing web applications—software accessed through a browser or HTTP API—using the OWASP Web Security Testing Guide approach. It starts with mapping the application before testing specific vulnerability types.

In plain words
What is it for?
Use it to discover endpoints and parameters, identify how inputs are handled, test authentication, run low-impact checks, and route confirmed issues to focused tests for problems such as SQL injection, cross-site scripting, or server-side request forgery.
Why use it?
It helps organize a large web application into pages, inputs, login areas, technologies, and data flows. This makes it easier to choose the right focused test and keep evidence of each result.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-app-pentest scanned grade A with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLlowData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -c cookies.txt -b cookies.txt https://target/login -d "user=test&pass=test"

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Web Application Pentest

Prerequisites

  • Target is in scope (scope/scope-master.txt, engagement ROE).
  • Load tier-3 vuln skills for payloads once a class is confirmed (see routing table below).

When to Use

  • Web application in scope with HTTP/HTTPS services
  • After hacktricks-methodology identifies web ports (80, 443, 8080, 8443)
  • Before diving into specific vuln skills (sqli, xss, ssrf, etc.)

Methodology

Task Progress:
- [ ] Map attack surface (endpoints, params, auth, tech stack)
- [ ] Classify input sinks (DB, shell, template, redirect, file, SSRF)
- [ ] Route to vuln skill; test with low-impact probes first
- [ ] Escalate only with evidence; document request/response proof

Phase 1: Surface mapping

Discovery

MSF MCP (preferred):

msf_run_auxiliary_module(
  module_name="auxiliary/scanner/http/http_version",
  engagement_id="<id>",
  options={"RHOSTS": "<target>", "RPORT": 443, "SSL": true}
)
msf_run_auxiliary_module(
  module_name="auxiliary/scanner/http/dir_scanner",
  engagement_id="<id>",
  options={"RHOSTS": "<target>", "RPORT": 443, "SSL": true, "PATH": "/admin", "DICTIONARY": "/usr/share/wordlists/dirb/common.txt"}
)
msf_db_nmap(
  engagement_id="<id>",
  targets="<target>",
  nmap_args="-sV -sC -p 80,443,8080"
)

CLI fallback:

ffuf -u https://target/FUZZ -w /path/wordlist.txt -mc 200,301,302,403
feroxbuster -u https://target -x js,html,json,php,asp
whatweb https://target
nuclei -u https://target -tags exposure,misconfig

Burp workflow notes

MSF: No direct module; use CLI/Burp.

CLI fallback:

1. Configure browser proxy to Burp (127.0.0.1:8080)
2. Browse target; let Burp build site map (Target > Site map)
3. Right-click > Scan (passive then active if ROE permits)
4. Send interesting requests to Repeater for manual mutation
5. Use Intruder for fuzzing (rate-limit per ROE)
6. Extensions: Autorize (authZ), Param Miner (hidden params), JWT Editor
7. Export evidence: right-click > Copy to file (request/response)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

web-app-pentest is a skill published in the GitHub repository Suzu-Testing/metasploit-cursor-harness (3 stars, last pushed 14d ago), licensed MIT. It adds 53 tokens to every session and 2,211 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
