Majordomo 2 _list_file_get() Function Traversal Arbitrary File Access

medium Nessus Plugin ID 52000
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 web server hosts a web application that contains a directory traversal vulnerability.

Description

The version of Majordomo 2 on the remote host fails to sanitize input to the 'extra' parameter of the 'mj_wwwusr' script before using it to return the contents of a file.

An attacker can leverage this issue using a directory traversal sequence to view arbitrary files on the affected host within the context of the web server. Information harvested may aid in launching further attacks.

Note that this issue is also reportedly exploitable through Majordomo's email interface, although Nessus has not checked for that.

Solution

Upgrade to Majordomo 2 build 20110204 or later.
