Summary
Fix CVE(s): CVE-2022-26923, CVE-2022-32743
Details
  • SECURITY UPDATE: Samba AD DC did not enforce the Validated-DNS-Host-Name write right, allowing an unprivileged authenticated user with machine account write access (e.g. SeMachineAccountPrivilege) to set the dNSHostName attribute to an arbitrary value, bypassing the MS-ADTS requirement that it match <sAMAccountName-sans-$>.<dnsDomainName>. This primitive is commonly chained with CVE-2022-26923 (Certifried) via AD CS to forge a machine certificate and escalate to Domain Admin.
