Activation

This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.

This skill should be used when the user asks to "test for directory traversal", "exploit path traversal vulnerabilities", "read arbitrary files through web applications", "find LFI vulnerabilities", or "access files outside web root". It provides comprehensive file path traversal attack and testing methodologies.

Key capabilities

  • Identify file path traversal vulnerabilities
  • Exploit directory traversal vulnerabilities
  • Read arbitrary files on a server
  • Bypass security restrictions
  • Escalate LFI to RCE
  • Implement prevention measures

How it works

The skill outlines a security testing methodology to find and exploit file path traversal vulnerabilities by passing user-controllable input to filesystem APIs without proper validation.

Inputs & outputs

You give it
User-controllable input passed to filesystem APIs
You get back
Identification and exploitation of file path traversal vulnerabilities, access to arbitrary files

When to use File Path Traversal Testing

  • Test for directory traversal
  • Exploit path traversal vulnerability
  • Check for LFI vulnerabilities
  • Identify security risk in filesystem access

About this skill

File Path Traversal Testing

Purpose

Identify and exploit file path traversal (directory traversal) vulnerabilities that allow attackers to read arbitrary files on the server, potentially including sensitive configuration files, credentials, and source code. This vulnerability occurs when user-controllable input is passed to filesystem APIs without proper validation.
