author: l0om page: l0om.org date: 14.02.2015 Cosmoshop is a simple webshop designed for the german market. There is a simple XSS flaw at the admin-login panel in probably all cosmoshop versions. The admin login can be found at http://www.shop-site.de/cgi-bin/cosmoshop/admin/index.cgi This page will show a typical login screen. The username field is filled with the value of "u_name". Since this parameter isn't filtered you can inject javascript code and trick someone to execute it. http://www.shop-site.de/cgi-bin/cosmoshop/admin/index.cgi?u_name=><script>alert("hello")</script> nothing special but better to know. Greetings and so long, l0om
