CWE-55Path Equivalence: '/./' (Single Dot Directory)

Category: other

Description

The product accepts path input in the form of single dot directory exploit ('/./') without appropriate validation, which can lead to ambiguous path resolution and allow an attacker to traverse the file system to unintended locations or access arbitrary files.

Common consequences· 1

  • Confidentiality / Integrity — Read Files or Directories, Modify Files or Directories

Potential mitigations· 1

  • [Implementation]Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
