Clickjacking vulnerability in CSRF error page pfSense

Abstract
------------------------------------------------------------------------
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.
------------------------------------------------------------------------
Tested versions
------------------------------------------------------------------------
This issue was successfully tested on pfSense version 2.4.1.
------------------------------------------------------------------------
Fix
------------------------------------------------------------------------
pfSense 2.4.2-RELEASE was released that addresses the Clickjacking
issue.
