Description

This module exploits a vulnerability in Internet Explorer Sandbox which allows to escape the Enhanced Protected Mode and execute code with Medium Integrity. The vulnerability exists in the IESetProtectedModeRegKeyOnly function from the ieframe.dll component, which can be abused to force medium integrity IE to user influenced keys. By using registry symlinks it's possible force IE to add a policy entry in the registry and finally bypass Enhanced Protected Mode.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
