The Cybersecurity and Infrastructure Security Agency (CISA) has released Emergency Directive 20-03 addressing a critical vulnerability—CVE-2020-1350—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.
Although Emergency Directive 20-03 applies only to certain Executive Branch departments and agencies, CISA strongly recommends state and local governments, the private sector, and others patch this critical vulnerability as soon as possible. Review the following resources for more information:
