CPE [?]: cpe:/a:microsoft:malware_protection_engine, cpe:/o:microsoft:windows
Exploited by Malware: True

Synopsis

The remote host has an antimalware application installed that is affected by a remote code execution vulnerability.

Description

The version of Microsoft Malware Protection Engine (MMPE) installed on the remote Windows host is prior to 1.1.13704.0. It is, therefore, affected by a remote code execution vulnerability in the NScript component in mpengine.dll due to a type confusion error. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to execute arbitrary code in the security context of the LocalSystem account.

Nessus has checked if a vulnerable version of MMPE is being used by any of the following applications :

- Microsoft Forefront Endpoint Protection 2010 - Microsoft Endpoint Protection - Microsoft Forefront Security for SharePoint - Microsoft System Center Endpoint Protection - Microsoft Security Essentials - Windows Defender for Windows 7, Windows 8.1, Windows RT 8.1, Windows 10, Windows 10 1511, Windows 10 1607, Windows 10 1703, and Windows Server 2016 - Windows Intune Endpoint Protection

Solution

Enable automatic updates to update the scan engine for the relevant antimalware applications. Refer to KB4022344 for information on how to verify MMPE has been updated.

How to Run

Here is how to run the MS Security Advisory 4022344: Security Update for Microsoft Malware Protection Engine as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

  1. Click to start a New Scan.
  2. Select Advanced Scan.
  3. Navigate to the Plugins tab.
  4. On the top right corner click to Disable All plugins.
  5. On the left side table select Windows plugin family.
  6. On the right side table select MS Security Advisory 4022344: Security Update for Microsoft Malware Protection Engine plugin ID 100051.
  7. Specify the target on the Settings tab and click to Save the scan.
  8. Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl smb_kb4022344.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a smb_kb4022344.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - smb_kb4022344.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state smb_kb4022344.nasl -t <IP/HOST>
