# Title: Vanilla Tagging Enchanced 1.0.1 Stored XSS # Date: 1/6/12 # Author: Henry Hoggard # Author URL: henryhoggard.co.uk # Author Twitter: @henryhoggard # Software: Vanilla Version 2.0.18.4 + Tagging Enhanced plugin 1.0.1 # http://vanillaforums.org/download # http://vanillaforums.org/addon/tagging-plugin This plugin is based on the default tagging plugin that comes with Vanilla. Therefore this is vulnerable to the same attack. Create a new thread and post your XSS as tag. I used <script>alert('xss')</script> You will have to use a proxy / manipulate the form to bypass the max-length on the form. Once you have posted the thread, send an administrator or moderator to http://target.tld/index.php?p=/vanilla/post/editdiscussion/7 Where 7 is the thread ID of the thread you just made. The XSS will then trigger. You can even use a URL shortener to send the link. Note: The URL may be different depending on what category your thread is in. #############################################################
