Vulnerability CVE-2020-1350

Vulnerability CVE-2020-1350

Microsoft released a security bulletin today detailing a RCE in all known Windows DNS Servers, with a base CVSS score of 10.0.

Datashield recommends patching any public facing windows DNS servers immediately. If patching isn’t possible, implementing the temporary workaround outlined Microsoft would mitigate the concern until a patch can be scheduled.

We do also recommend patching internal windows DNS servers as well, as once a POC is published, this will be a common avenue for lateral movement in windows environments by both malware and penetration testers alike once a POC is announced.

Our content team will be developing an alert for this CVE for future detections.
