Senserva AI Opinion for CVE-2025-49672

RRAS parses complex routing and tunneling protocols designed decades ago, and this Critical 9.8 remote code execution flaw on Server 2019 and 2022 is the predictable result. A 22% EPSS score keeps it in the priority tier even without confirmed attacks.

Do this: Disable RRAS on servers where the role was enabled but never used; that removes this bug and its siblings in one step.
