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

medium Nessus Plugin ID 35328
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
