As the slogan of this blog says there’s always a crack in everything, that’s how the light gets in, yes, it’s true, even on Facebook, there’re some holes left. The secret is left behind their application module. Around last November, 2009, holes for tweaking facebook found when i was looking for bugs, and the XSS was firstly only for IE + old Fx browser only.

Screenshot :

After sometime, a bug is also found in the wall (clickjacking) XSS is loaded with the click (this is more risky because it appeared in the feed all the friends / home.php). At present apart from the wall, there’re around 7 XSS variation found in facebook that have not been patched (3 For IE & old Fx Only and 4 crossbrowsers) and probably many more. At first it was only used for changing content sidebar, without external scripting, and the code is really personal and not intended be shared, why? notice the address of facebook profile : http://www.facebook.com/blahblah this may allow event load on profile to access information on main domain, quite risky. Too much malicious coder around us.

To facebook users, be careful with the existence of these security holes, this shows us that anyone can do more when you visit the profile, frankly I only use it for a small modification of the layout of my profile, nothing more. To friends, coder or any who will find or may have found the same bug, please keep silent. Facebook is very comfortable even without XSS for page tweaking, hope it will still be like that.

    This is certainly one of the most remarkable blogs I have seen. It’s so easy to tune out, but there is really some first-rate information online, and I think your place is one of the few!
