This vulnerability, discovered by Check Point researchers, had received a score of 10/10, a sign of an extreme severity of the risk for unpatched computers: it could in fact be used to create self-replicating malware. Other vulnerabilities fixed concerned the RemoteFX vGPU component, which is part of Microsoft Hyper-V technology, and various security issues in Word, Excel, Outlook, Sharepoint and various graphics components of Windows.

How the CVE-2020-1350 vulnerability works

La CVE-2020-1350 vulnerability it was discovered by Check Point and renamed “SigRed“. Its severity derives from the fact that it can be exploited to create a “worm” type of malware, which spreads by itself and without control from one computer to another, infecting them all. If a malware like that were to sneak into a corporate network, then very quickly all of the company's computers would be compromised. By exploiting this vulnerability a hacker could have done artfully packaged DNS requests to force Windows DNS servers to execute malicious code, which could then infiltrate other machines connected to the network.
