high Nessus Plugin ID 66986

Language:

Synopsis

The remote web server hosts a PHP script that allows arbitrary command execution.

Description

The version of FreePBX hosted on the remote web server is affected by a remote command injection vulnerability due to a weakness in the 'strpos' function when sanitizing user-supplied input to the 'dir' parameter in 'page.backup.php'. A remote, unauthenticated attacker can exploit this issue to execute arbitrary commands on the remote host, subject to the privileges of the web server user.

Solution

Upgrade FreePBX to version 2.10 or later.
