Serv-U 7.x < 7.4.0.0 Multiple Command Remote DoS

medium Nessus Plugin ID 35328

Language:

Synopsis

The remote FTP server is affected by a denial of service vulnerability.

Description

The installed version of Serv-U 7.x is earlier than 7.4.0.0, and is therefore affected by a denial of service vulnerability. By using a specially crafted command such as XCRC, STOU, DSIZ, AVBL, RNTO, or RMDA, it may be possible for an authenticated attacker to render the FTP server temporarily unresponsive.

Solution

Upgrade to Serv-U version 7.4.0.0 or later.
