Technical Analysis

Privilege escalation in Active Directory Domain Services that allows for elevation of privilege across a network.

Given how popular Active Directory is this is pretty serious and I imagine this will likely be a very popular way to escalate privileges in internal engagements should an exploit come out for this.

Bug is noted as being related to Active Directory Domain Service environments that have incoming trusts, and that the bug allows attackers to escalate privileges across the trust boundary under certain conditions.

The fact that this is labeled as “under certain conditions” leads me to believe that this may not be a default configuration which is why I have labeled it as such in my report. However I would also provide a slight counterpoint to this in that AD networks are often sprawling and complex so there is a good likelihood that this may be enabled in some part of the network even if you are not aware of it.

Definitely one to patch if you are running AD networks.
