DESCRIPTION: Kingcope has discovered a vulnerability in Serv-U, which can be exploited by malicious users to disclose potentially sensitive information and manipulate certain data.

The vulnerability is caused due to an input sanitisation error within the FTP server and can be exploited to e.g. download or delete files outside of the FTP's root directory via directory traversal attacks.

The vulnerability is confirmed in version 10.3.0.1 and 11.1.0.3 on Windows. Other versions may also be affected.

SOLUTION: Restrict access to trusted users only.
