Security experts are sounding the alarm over a new, very critical, Windows DNS security flaw dubbed “SIGRed”, or more distinctly “CVE-2020-1350”. This specific vulnerability has the rare distinction of receiving a perfect 10 severity score according to the Common Vulnerability Scoring System, or CVSS.

Microsoft themselves state regarding this vulnerability:

We consider this to be a wormable vulnerability, meaning that it has the potential to spread via malware between vulnerable computers without user interaction. DNS is a foundational networking component and commonly installed on Domain Controllers, so a compromise could lead to significant service interruptions and the compromise of high level domain accounts.
