Senserva AI Opinion for CVE-2025-33066

This companion RRAS remote code execution flaw shares the alarming 82% EPSS estimate and the same Windows 10 1809 and Windows Server 2019 footprint, at High Severity, CVSS 8.8. When two parallel bugs both score that high, exploit development against the component is very likely underway.

Do this: Verify the update covering this flaw is fully deployed, then disable RRAS on any 1809 or Server 2019 machine that does not need it.
