Description

A vulnerability in Cerberus FTP Server allows an authenticated remote attacker to perform UNC path injection via a manipulated parameter. By supplying a malicious SMB share path, an attacker can execute authentication coercion against the underlying server, resulting in the leakage of the Cerberus service account's Net-NTLMv2 hash. This issue has been resolved in Cerberus FTP Server: 2026.3.0.
