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 FTP server installed on the remote Windows host has a security bypass vulnerability.

Description

The version of Cerberus FTP server on the remote host is earlier than 4.0.3.0. Such versions are potentially affected by a security bypass vulnerability. The 'MLSD' and 'MLST' commands list hidden files despite the 'Display hidden files' option being disabled. A remote attacker, possibly uncredentialed, may be able to leverage this issue to enumerate hidden files on the affected system.

Solution

Upgrade to Cerberus FTP server 4.0.3 or later.
