Common Weakness Enumeration
- CWE-36 - Absolute Path TraversalThe software uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" that can resolve to a location that is outside of that directory.
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')The software uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the software does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
