CISA releases emergency directive on critical Microsoft vulnerability

The Department of Homeland Security Cybersecurity and Infrastructure Security Agency (CISA) has released an emergency directive addressing a critical vulnerability affecting all versions of Windows Server with the Domain Name System (DNS) role enabled. A remote attacker could exploit this vulnerability to take control of an affected system. This vulnerability is considered “wormable” because malware exploiting it on a system could, without user interaction, propagate to other vulnerable systems. CISA strongly recommends state and local governments, the private sector, and others patch this critical vulnerability as soon as possible.
