If you are using any supported version of the Windows operating system, stop everything and install the latest security updates from Microsoft immediately.
Windows operating system contains four new critical wormable, remote code execution vulnerabilities in Remote Desktop Services, similar to the recently patched ‘BlueKeep‘ RDP vulnerability.
Discovered by Microsoft’s security team itself, all four vulnerabilities, CVE-2019-1181, CVE-2019-1182, CVE-2019-1222, and CVE-2019-1226, can be exploited by unauthenticated, remote attackers to take control of an affected computer system without requiring any user interaction.
Just like BlueKeep RDP flaw, all four newly discovered vulnerabilities are also wormable and could be exploited by potential malware to propagate itself from one vulnerable computer to another automatically.
