Title: Cerberus FTP Server Information Disclosure Weakness
Severity: MODERATE
Description:
Cerberus FTP Server is an FTP server designed to provide powerful, multithreaded FTP server performance for a desktop user.
It has been reported that Cerberus FTP Server is prone to an information disclosure weakness.
The problem exists in the way the FTP server handles the authentication procedure. Specifically the FTP server returns a '530 Unknown user' error message to the console, if the username supplied is invalid, before disconnecting the user. An attacker may exploit this weakness to disclose valid usernames.
It should be noted that although this weakness was reported to affect Cerberus FTP server version 2.1, previous versions might also be affected.
Affected Products:
- Cerberus FTP Server 2.1.0
