Netlogon Domain Controller Enforcement Mode is enabled by default beginning with the February 9, 2021 Security Update, related to CVE-2020-1472

Thursday, January 14, 2021

Microsoft addressed a Critical RCE vulnerability affecting the Netlogon protocol (CVE-2020-1472) on August 11, 2020. We are reminding our customers that beginning with the February 9, 2021 Security Update release we will be enabling Domain Controller enforcement mode by default. This will block vulnerable connections from non-compliant devices. DC enforcement mode requires that all Windows and non-Windows devices use secure RPC with Netlogon secure channel unless customers have explicitly allowed the account to be vulnerable by adding an exception for the non-compliant device.

Attacks exploiting Netlogon vulnerability (CVE-2020-1472)

Microsoft has received a small number of reports from customers and others about continued activity exploiting a vulnerability affecting the Netlogon protocol (CVE-2020-1472) which was previously addressed in security updates starting on August 11, 2020.

Patch new wormable vulnerabilities in Remote Desktop Services (CVE-2019-1181/1182)

Tuesday, August 13, 2019

Today Microsoft released a set of fixes for Remote Desktop Services that include two critical Remote Code Execution (RCE) vulnerabilities, CVE-2019-1181 and CVE-2019-1182. Like the previously-fixed ‘BlueKeep’ vulnerability (CVE-2019-0708), these two vulnerabilities are also ‘wormable’, meaning that any future malware that exploits these could propagate from vulnerable computer to vulnerable computer without user interaction.
