File Path Traversal

This is a comprehensive offensive security skill for finding and exploiting path traversal vulnerabilities during authorized pentests. It walks through identification of vulnerable file parameters, basic exploitation with payloads like `../../../etc/passwd`, bypass techniques for common filters (null bytes, encoding variations, nested sequences), and platform-specific target files for both Linux and Windows systems. The workflow includes automated testing with ffuf and Burp Suite, plus escalation techniques like log poisoning to achieve remote code execution. It's thorough on the attack mechanics but light on defensive remediation details, so you'll want separate resources if you're trying to fix these vulnerabilities rather than find them.
