Windows 10: How to find the version of the Microsoft Malware Protection Engine

¡Firedog · Feb 28, 2019

We used to be able to see the versions of the important WD files in the Security Centre. In Windows 10 1809, build 17763.316, I can't find them anywhere.

It's probably too much to expect that the ubiquitous file MsMpEng.exe is the Microsoft Malware Protection Engine, despite its name. Anyway, its version no. (4.18.1807.18075) doesn't fit the pattern I was looking for.

A recent Windows Security bulletin describes a fault that 'occurs only on computers that are protected by the 1.1.15700.xversion of Microsoft Malware Protection Engine:'

Applications that depend on Task Scheduler stop responding published 25 February 2019.

The article fails to explain how to find out whether a particular computer is affected. Does anyone know how to find the version of the Microsoft Malware Protection Engine installed on my computer?

Microsoft Malware Protection Engine Remote Code Execution Vulnerability - CVE-2017-0290

A remote code execution vulnerability exists when the Microsoft Malware Protection Engine does not properly scan a specially crafted file leading to memory corruption.

An attacker who successfully exploited this vulnerability could execute arbitrary code in the security context of the LocalSystem account and take control of the system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, a specially crafted file must be scanned by an affected version of the Microsoft Malware Protection Engine. There are many ways that an attacker could place a specially crafted file in a location that is scanned by the Microsoft Malware Protection Engine. For example, an attacker could use a website to deliver a specially crafted file to the victim's system that is scanned when the website is viewed by the user. An attacker could also deliver a specially crafted file via an email message or in an Instant Messenger message that is scanned when the file is opened. In addition, an attacker could take advantage of websites that accept or host user-provided content, to upload a specially crafted file to a shared location that is scanned by the Malware Protection Engine running on the hosting server.

If the affected antimalware software has real-time protection turned on, the Microsoft Malware Protection Engine will scan files automatically, leading to exploitation of the vulnerability when the specially crafted file scanned. If real-time scanning is not enabled, the attacker would need to wait until a scheduled scan occurs in order for the vulnerability to be exploited. All systems running an affected version of antimalware software are primarily at risk.

The update addresses the vulnerability by correcting the manner in which the Microsoft Malware Protection Engine scans specially crafted files.

Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security advisory was originally issued.

Suggested Actions

Verify that the update is installed
Customers should verify that the latest version of the Microsoft Malware Protection Engine and definition updates are being actively downloaded and installed for their Microsoft antimalware products.

For more information on how to verify the version number for the Microsoft Malware Protection Engine that your software is currently using, see the section, "Verifying Update Installation", in Microsoft Knowledge Base Article 2510781.

For affected software, verify that the Microsoft Malware Protection Engine version is 1.1.13704.0 or later.

If necessary, install the update
Administrators of enterprise antimalware deployments should ensure that their update management software is configured to automatically approve and distribute engine updates and new malware definitions. Enterprise administrators should also verify that the latest version of the Microsoft Malware Protection Engine and definition updates are being actively downloaded, approved and deployed in their environment.

For end-users, the affected software provides built-in mechanisms for the automatic detection and deployment of this update. For these customers, the update will be applied within 48 hours of its availability. The exact time frame depends on the software used, Internet connection, and infrastructure configuration. End users that do not wish to wait can manually update their antimalware software.

For more information on how to manually update the Microsoft Malware Protection Engine and malware definitions, refer to Microsoft Knowledge Base Article 2510781.
