THE THREAT

Update 2020/04/16: On April 14, 2020, Microsoft released security patches for both of the vulnerabilities mentioned in this advisory (CVE-2020-0938, CVE-2020-1020). After performing a business impact review, organizations should apply the latest Microsoft security patches to avoid impact.

Microsoft has announced two un-patched vulnerabilities affecting all supported versions of Windows and Windows Servers [1]. Limited attacks exploiting the vulnerabilities have been identified in the wild. If exploited, a remote and unauthenticated attacker could execute code on vulnerable systems. Successful exploitation could lead to the full compromise of targeted devices. Microsoft is actively developing a security patch for these vulnerabilities; once released, applying the patches should be high priority for organizations.
