Directory traversal attack is a web application vulnerability allowing attackers to access sensitive OS files by manipulating URL parameters. The blog explains how these attacks work with examples, real-world scenarios, and effective mitigation strategies. #DirectoryTraversal #PathTraversal
Keypoints
- Directory traversal exploits URL parameters to access restricted files on the server.
- Attackers often use payloads like ../ to navigate up directories in the file system.
- Sensitive files such as /etc/passwd and /etc/shadow are common targets for extraction.
- Mitigation includes using whitelists, blocking dangerous patterns, and restricting access to specific directories.
- Proper use of safe path functions and limited user permissions help prevent such vulnerabilities.
