Description

Microsoft has a security solution called "Enhanced Mitigation Experience Toolkit" (EMET) that it releases for use to protect potentially vulnerable software to disable zero-day exploits from being effected. A critical vulnerability has been located in EMET where an attacker can completely bypass the protections the software provides to install malware or perform alterations to the system. The discovered vulnerability effectively utilizes "detours" around the checks, thus bypassing the protections.

  • EMET 4.1 is vulnerable, it's assumed prior versions are also.

Mitigation/Solution

Users should be cautious on what input or files they are utilizing with any software at all times and not rely on security solutions to be a sole protection. It is advised to only open files that one knows the original source and is able to verify the legitimacy of those files before using the file in any capacity.
