GNU Mailman < 2.1.6 Directory Traversal Arbitrary File Access

Medium

Synopsis

The remote host is vulnerable to a flaw that allows attackers to retrieve sensitive files or data

Description

The remote host is running GNU Mailman, a web based software to manage mailing lists. There is a flaw in this version of Mailman that would allow a remote attacker to retrieve potentially confidential data. Specifically, the CGI script 'private.py' does not properly parse user-supplied data and would allow an attacker to read any file on the operating system that was readable by the web process.

Solution

Upgrade to version 2.1.6 or higher.
