'Name'=> 'Clickjacking Vulnerability In CSRF Error Page pfSense',
'Description' => %q{
This module exploits a Clickjacking vulnerability in pfSense <= 2.4.1.
pfSense is a free and open source firewall and router. It was found that the
pfSense WebGUI is vulnerable to Clickjacking. By tricking an authenticated admin
into interacting with a specially crafted webpage it is possible for an attacker
to execute arbitrary code in the WebGUI. Since the WebGUI runs as the root user,
this will result in a full compromise of the pfSense instance.
