Description:
Benjamin Tobias Franz has discovered a vulnerability in Internet Explorer, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to certain objects not being initialized correctly when the "window()" function is used in conjunction with the "<body onload>" event. This can be exploited to execute arbitrary code on a vulnerable browser via some specially crafted JavaScript code called directly when a site has been loaded.
Example:
<body onload="window();">
Successful exploitation requires that the user is e.g. tricked into visiting a malicious website.
The vulnerability has been confirmed on a fully patched system with Internet Explorer 6.0 and Microsoft Windows XP SP2, and Internet Explorer 6.0 and Microsoft Windows 2000 SP4.
Note: A PoC exploit has been released for this vulnerability.
