Subject: Internet Explorer Code Execution Bypass Vulnerability




Last week I discovered a vulnerability to avoid/overrun/bypass the new protection for Local JS Execution on IE (winxp sp2)

--cut here--

&lt;script&gt;
window.alert("Example Exploit");
&lt;/script&gt;

--cut here--

(Copy and paste into your Notepad and save it as EXAMPLE.HTM)

If you open EXAMPLE.HTM, your IE blocks this code and shows a yellow bar over the webpag.

But I discovered a vulnerability to allow Local JS Code to execute on IE, the exploit is:

"Go to Control Panel / Display Config and set as the desktop background the example webpage (EXAMPLE.HTM), once this is done, the code will be executed without showing any warning in IE"
