Weakness Name

Path Traversal: '/../filedir'

Description

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize "/../" sequences that can resolve to a location that is outside of that directory.

This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory. Sometimes a program checks for "../" at the beginning of the input, so a "/../" can bypass that check.

Common Consequences

Scope: Confidentiality, Integrity

Impact: Read Files or Directories, Modify Files or Directories
