SAP NetWeaver (Knowledge Management), versions (KMC-CM - 7.00, 7.01, 7.02, 7.30, 7.31, 7.40, 7.50 and KMC-WPC 7.30, 7.31, 7.40, 7.50), does not sufficiently validate path information provided by users, thus characters representing traverse to parent directory are passed through to the file APIs, allowing the attacker to overwrite, delete, or corrupt arbitrary files on the remote server, leading to 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.
