By May 9, 2023, all devices will be updated to Full Enforcement mode. If no audit event logs are created on domain controllers for one month after installing the update, proceed with enabling Full Enforcement mode on all domain controllers. The update will provide audit events that identify certificates that are not compatible with Full Enforcement mode. Update all servers that run Active Directory Certificate Services and Windows domain controllers that service certificate-based authentication with the update (see Compatibility mode). To protect your environment, complete the following steps for certificate-based authentication: Additionally, conflicts between User Principal Names (UPN) and sAMAccountName introduced other emulation (spoofing) vulnerabilities that we also address with this security update. This allowed related certificates to be emulated (spoofed) in various ways. Less SummaryĬVE-2022-26931 and CVE-2022-26923 address an elevation of privilege vulnerability that can occur when the Kerberos Distribution Center (KDC) is servicing a certificate-based authentication request. Before the security update, certificate-based authentication would not account for a dollar sign ($) at the end of a machine name.
