SquirrelMail S/MIME Plug-in Remote Command Execution

medium Nessus Plugin ID 17257

Language:

Synopsis

The remote web server contains a PHP script that is prone to arbitrary command execution attacks.

Description

The S/MIME plugin for SquirrelMail installed on the remote host does not sanitize the 'cert' parameter used by the 'viewcert.php' script. An authenticated user can exploit this flaw to execute system commands remotely in the context of the web server.

Solution

Upgrade to version 0.6 or later of the plugin.
