Detailsinfo

A vulnerability, which was classified as critical, has been found in SAP Knowledge Management up to 7.50 (Knowledge Base Software). Affected by this issue is an unknown function of the component File API. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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 weakness was released 04/14/2020. This vulnerability is handled as CVE-2020-6225 since 01/08/2020. The attack may be launched remotely. The successful exploitation requires a simple authentication. The technical details are unknown and an exploit is not available.
