high Nessus Plugin ID 52456
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


A vulnerable version of Microsoft Malware Protection Engine (MMPE) is installed on the remote system. MMPE is typically included with Microsoft anti-malware products such as Windows Live OneCare, Microsoft Security Essentials, Microsoft Forefront Client Security, Microsoft Forefront Client Security, Microsoft Forefront Endpoint Protection 2010, and Microsoft Malicious Software Removal Tool.

A local user may be able to gain local system privileges by creating a specially crafted registry key before a system is scanned using Microsoft Malware Protection Engine.


Update the malware definitions for the installed Microsoft anti- malware product.
