Senserva AI Opinion for CVE-2020-1472
This Netlogon privilege escalation is one of the most consequential Windows vulnerabilities ever cataloged: an attacker who can reach a domain controller over the network can establish a vulnerable Netlogon secure channel and effectively take over the domain. It is confirmed exploited and used in ransomware campaigns, where it remains a favorite for going from one infected workstation to full Active Directory control in minutes. No patched environment should ever see this again, yet unpatched domain controllers keep turning up.
Do this: Verify every domain controller enforces Netlogon secure channel protections and alert on any denied vulnerable connections.
