Senserva AI Opinion for CVE-2024-38126

This NAT denial-of-service flaw rates Critical 9.8 with a 71 percent EPSS score on Windows 10 1809 and Server 2019. Alongside the NAT RCE in the same cycle, it means hosts running network address translation face both crash and code-execution risk. A crafted packet can disrupt routing for everything behind the NAT. No ransomware association exists.

Do this: Patch NAT-serving Server 2019 hosts for both the NAT DoS and NAT RCE fixes in one update, and segment NAT routers away from untrusted traffic.
