On 7/29/13 I've reported Live.com XFO vulnerability to the *Microsoft Security team* and finally their investigation came to conclusion and fixed the bug. So, Here is details of bug and timeline of fixing bug. A year ago on the weekend, I started digging into MS services for bugs. The timeline of investigation of the bug : July 29, 2013 - April 16 , 2014. [image: Name: msresponse.jpg Views: 202 Size: 23.1 KB] The interesting part of the vulnerability all pages were protected for * UI Addressing Attack * and while doing testing, normally I test application on the all browsers. The weird part comes here, I was able to iframe the all the pages of Live.com including pre-authentication and post-authentication pages on Mozilla Firefox 3.6.28 to Mozilla Firefox 6. On Chrome and on other browser all pages functionality of XFO was working perfectly. Random announcement , nothing do with this post : Check out recorded video of Garage4Hackers Ranchoddas Webcast Series - Browser Crash Analysis By David Rude II aka Bannedit Note : Have look the same vulnerability on Facebook Application Installing Obviously , you must be thinking why this thing is happening with Mozilla. After doing some research and consulting with *G4H team* , I've concluded, it may be issue with *Gecko Engine*. The test environment was win 7 , ubuntu 10,11,12. Note : If you stumbled upon on the same issue of Gecko, then please do reply on this thread. Check out the following headers , XFO header is missing on Gecko/20120306 Firefox/3.6.28 to MF 6.
