Patch Now: Remediate the Zerologon Vulnerability

A vulnerability dubbed “Zerologon,” first seen in Microsoft’s August Patch Tuesday security updates, is getting renewed attention due to additional context released by the security organization, Secura. CVE-2020-1472, is a critical CVSS10 vulnerability that allows a malicious threat actor on a corporate network to impersonate the identity of any network computer trying to authenticate against a domain controller, disable related Netlogon security features, and change password credentials on network domain controllers.

Microsoft is addressing the vulnerability in a two-stage process: the first was delivered in the August “Patch Tuesday” release which stages the capability to address the vulnerability; and, the second update is slated for Q1 2021 to toggle enforcement. This approach is to allow for non-Windows device implementations time to address the protocol changes.

Automox strongly encourages the prioritization of applying the August 2020 security update and also deploying the Domain Controller (DC) enforcement mode before the Q1 2021 update to ensure they have minimized the risk of this vulnerability until the complete patch is available.
