CWE-25: Path Traversal: '/../filedir'

ID CWE-25

Abstraction Variant

Structure Simple

Status Incomplete

Number of CVEs 7

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.
