Techniques & Countermeasures

• CWE-22•Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

  The product 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 product 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.

• CWE-61•UNIX Symbolic Link (Symlink) Following

  The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.
