CWE-28—Path Traversal: '..\filedir'

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. The '..\' manipulation is the canonical manipulation for operating systems that use "\" as directory separators, such as Windows. However, it is also useful for bypassing path traversal protection schemes that only assume that the "/" separator is valid.

Common Consequences
