unauthorized-access-common-services

unauthorized-access-common-services is a skill for Claude Code, Codex from DorianGallo/hack-skills-local. It costs 49 tokens per session (2,828 once invoked), scanned A, a copy of unauthorized-access-common-services, MIT.

A security guide to attacking exposed services that accept administrative requests without proper authentication, including Redis, Rsync, PHP-FPM, and Hadoop YARN.

In plain words
What is it for?
It is for assessing exposed service ports, checking authentication, and investigating service-specific paths to file access or code execution.
Why use it?
It helps identify infrastructure that can allow data theft or command execution because a management interface is reachable without reliable access control.

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

unauthorized-access-common-services 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 6d 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.

SKILL: Unauthorized Access to Common Services — Expert Attack Playbook

AI LOAD INSTRUCTION: Expert techniques for exploiting unauthenticated or weakly authenticated management services. Covers Redis write-to-RCE, Rsync data theft, PHP-FPM code execution, Ghostcat AJP file read, Hadoop YARN job submission, and H2 Console JNDI. These are infrastructure-level findings distinct from web application vulnerabilities.

Comprehensive Port Reference

  • Full exploitation matrix organized by port number (20+ services)
  • Enumeration, brute force, and post-exploitation per service
  • Quick triage during nmap/masscan output analysis
