• In a man-in-the-middle attack, an attacker can spoof the contents or the location of a proxy auto configuration (PAC) file and then inject code into the currently running application, bypassing the Code Access Security (CAS) restrictions. (CVE-2012-4776)

Impact of Attack • An attacker could take complete control of the affected system.

Mitigating Factors• By default, IE 9 and IE 10 prevent XAML, which is used by XBAPs, from running in the Internet Zone.• By default, IE 6, IE 7, and Internet Explorer 8 are configured to prompt the user before running XAML, which is used

by XBAPs in the Internet Zone.
