Directory Traversal
A Directory Traversal attack targets HTTP traffic and allows the attacker to access directories outside the applications own, potentially exposing sensitive system files to leakage or overwriting. This is also known as Directory Climbing, Path Traversal, or Backtracking. An alert on this kind of attack indicates a vulnerability in security validation of user input that allows a "traverse to parent directory" or "../" command to pass through. Protect your site by filtering all user input, removing any characters but the allowed data.
