Tracked as CVE-2020-1472 and addressed on August 2020 Patch Tuesday, the critical vulnerability was identified in the Microsoft Windows Netlogon Remote Protocol (MS-NRPC) and can be abused to compromise Active Directory domain controllers and gain admin access.
Exploitable by unauthenticated attackers able to run a specially crafted application on a device on the network, the vulnerability came into the spotlight in September, after the Department of Homeland Security (DHS) told federal agencies to immediately apply patches for it.
Attacks targeting the vulnerability were observed soon after, and Microsoft issued guidance on how organizations can secure systems affected by the bug. Attacks targeting Zerologon, however, continued.
