Overview​

Allow ACEs that grant GenericAll, WriteDacl, WriteOwner, or ExtendedRight can enable high-impact control over Active Directory objects. These permissions are commonly involved in privilege escalation and persistence paths.

  • GenericAll: Grants broad control over the object.
  • WriteDacl / WriteOwner: Enables permission tampering or ownership takeover.
  • ExtendedRight: May allow sensitive control-access operations depending on object type.

Security Recommendation​

Limit privileged rights to tightly controlled administrative groups. Investigate unexpected identities or objects that accumulate these permissions.

How the Test Works​

This test reads DaclEntries from Get-MtADDomainState, filters to allow ACEs, and counts entries where ActiveDirectoryRights includes GenericAll, WriteDacl, WriteOwner, or ExtendedRight.
