eTicket 1.5.5.2 Multiple Vulnerabilities
======================================================================
Author: L4teral <l4teral [4t] gmail com>
Impact: Cross Site Scripting
Cross Site Request Forgery
SQL Injection
Status: patch not available
------------------------------
Affected software description:
------------------------------
Application: eTicket
Version: 1.5.5.2 (other versions may also be affected)
Vendor: http://eticket.sourceforge.net
Description:
eTicket is a PHP-based electronic (open source) support ticket system
based on osTicket, that can receive tickets via email (pop3/pipe) or
a web form. It also offers a ticket manager with many features.
An ideal helpdesk solution for any website.
--------------
Vulnerability:
--------------
1. The variable 's' is not properly sanitized leading to
cross site scripting.
2. The script admin.php is prone to sql injections (admin
privileges required).
3. The search of the application is prone to sql injection, which
can be used to obtain login credentials or perform other
malicious taks.
The parameters 'status', 'sort' and 'way' are not properly
sanitized before being used in a sql query.
Exploitation requires valid user credentials, but as any user
is able to create a ticket, an attacker can obtain valid login
data without any problems.
4. The application is vulnerable to cross site request forgery.
Combined with the "my account" part of the application
being prone to sql injection, the password of an admin
account can be set to an arbitrary value by just visiting
a specially crafted website wile being logged in to the
application. Normally, the current password has to be entered
to change the password of an account. This can be circumvented
in the described way by combining the two vulnerabilities.
