XSSed Orkut after Twitter after Facebook <xss/>

'Are you social?'
ohhh... let me rephrase it 'Are you net-social?'
yeah... then how much socially secure are you when the plain-text attacks are htting millions.

2 months back with Facebook
now almost treated as synonym of Social Networking, and more than 400 million active users... Facebook was exposed to be vulnerable of a XSS vulnerability instead of proper implementation of HTTPOnly cookie protection as that doesn't count for XSS. The PoC video is being linked below along with article.

Video Demo of the same PoC: http://www.youtube.com/watch?v=ENiiAccY1v0


I was working on a XSS-Patch PoC, which I now feel works proper enough to prove its point.
This neither require Web-Developers for any Filtering/Validation, nor any javascript blocking add-on on user's browser.

I'm not good at explaining still I've tried to do that in the above linked WhitePaper.

And the ZIP file can be extracted, having 'StartDemo.bat' to be executed to start the server already patched with XSS Subverting Module.
Then browse, 'http://localhost/tweet.htm' in any browser... and it lets you Submit any text to Server w/o validation which is as it is saved there. But when retrieved on 'Read...' remains inactive for any
