BackToFramedJpu - a successor of BackToJpu attack [tested] OS:Win2k3,CN version IE: with MS03-048 installed. OS:WinXp, CN version Microsoft Internet Explorer v6.Sp1; up-to-date on 2003/11/16 [overview] A cross-zone scripting vulnerability has been found in Internet Explorer. If a webpage contains some subframe(either FRAME tag or IFRAME tag), its security zone may be compromised. [demo] There is a harmless demo: http://www.safecenter.net/UMBRELLAWEBV4/BackToFramedJpu/BackToFramedJpu-MyPage.htm [technical details] After applying MS03-048 patch, no javascript-protocol URL won't be stored in URL history list any more, which means classical "javascript-protocol URL in history" attack doesn't work any more. (Liu Die Yu's http://www.safecenter.net/UMBRELLAWEBV4/BackMyParent2/index.html) However, if an attacker do the following things: Navigate a sub-frame in victim document to a javascript-protocol URL, (first, navigate sub-frame to attacker's page, and then navigate the sub-frame a javascript-protocol URL) and then navigate the top window away, At last,navigate back("history.back()"). the javascript-protocol URL will be loaded by the top window(victim document) and script in the javascript-protocol URL will be executed in the security zone of victim document - a.k.a cross-site/zone/domain scripting [Workaround] Disable Active Scripting in INTERNET zone.

[Employment] I would like to work professionally as a security researcher/bug finder. See my resume at my site. I am very eager to work, flexible, and extremely productive. I have a top notch resume, with credentials from leading bug finders. I am willing to work per contract, relocate, or telecommute. [Give a Hand] I haven't got a job as a security researcher yet and my family don't support my security work - so, I don't have a computer of my own.
