SYMPTOMS
A script that is embedded in a cookie could be run in the wrong zone. This elevation-of-privilege vulnerability exists in the zone-determination policy function in Internet Explorer. Specifically, the script could run in the My Computer zone.

Internet Explorer zone security is a system that you can use to divide online content into categories, or zones. You can assign specific Web sites to each zone, depending on how much you trust the content of each site. Internet Explorer includes predefined security zones for the Local Intranet zone, the Trusted Sites zone, the Internet zone, and the Restricted Sites zone. In addition, the My Computer zone includes everything on the client computer, which is typically the contents of the hard disk and removable-media drives.



CAUSE
This vulnerability occurs because the function that performs zone-determination policy does not correctly assign the script that is embedded in a cookie to run in the Internet zone.
