Note If you are using Windows Server 2008 R2 SP1, you need an Extended Security Update (ESU) license to successfully install any update that addresses this issue. UPDATE your Domain Controllers with an update released Augor later.įIND which devices are making vulnerable connections by monitoring event logs.ĪDDRESS non-compliant devices making vulnerable connections.ĮNABLE enforcement mode to address CVE-2020-1472 in your environment. At that time, you will not be able to disable enforcement mode. Warning Starting February 2021, enforcement mode will be enabled on all Windows Domain Controllers and will block vulnerable connections from non-compliant devices. To fully mitigate the security issue for third-party devices, you will need to complete all the steps. Note Step 1 of installing updates released Augor later will address security issue in CVE-2020-1472 for Active Directory domains and trusts, as well as Windows devices. To protect your environment and prevent outages, you must do the following: To learn more about the vulnerability, see CVE-2020-1472. This includes read-only domain controllers (RODC). To provide AD forest protection, all DCs, must be updated since they will enforce secure RPC with Netlogon secure channel. This security update addresses the vulnerability by enforcing secure RPC when using the Netlogon secure channel in a phased release explained in the Timing of updates to address Netlogon vulnerability CVE-2020-1472 section. These updates enforce the specified Netlogon client behavior to use secure RPC with Netlogon secure channel between member computers and Active Directory (AD) domain controllers (DC). MS-NRPC includes an authentication method and a method of establishing a Netlogon secure channel. The Netlogon Remote Protocol (also called MS-NRPC) is an RPC interface that is used exclusively by domain-joined devices.
