A security feature bypass vulnerability exists when Internet Explorer fails to validate the correct Security Zone of requests for specific URLs. This could allow an attacker to cause a user to access a URL in a less restricted Internet Security Zone than intended.

To exploit this vulnerability, an attacker could email or otherwise provide a specially crafted URL to a victim and convince them to click on it.

The security update addresses the vulnerability by correcting security feature behavior to properly map affected URLs to the correct Security Zone.
