BackToFramedJpu - a successor of BackToJpu attack
[tested]

[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.

A wise man learns from other's mistakes; a fool learns from his own.
[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. Please consider about donating at:
