MS KB3074162: Vulnerability in Microsoft Malicious Software Removal Tool Could Allow Elevation of Privilege

High Nessus Plugin ID 84742

Synopsis

The remote Windows host has an antimalware application that is affected by a privilege escalation vulnerability.

Description

The remote Windows host is affected by an elevation of privilege vulnerability due to the Malicious Software Removal Tool (MSRT) failing to properly handle a race condition involving DLL-planting.
An authenticated attacker can exploit this vulnerability by placing a specially crafted DLL file in a local directory that is later run by MSRT, resulting in an elevation of privileges.

Solution

Enable automatic updates to update the scan engine for the relevant antimalware applications. Refer to KB2510781 for information on how to verify MMPE (and the associated MSRT) has been updated.
