Summary

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.

CWE-22 - Path Traversal

Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
