Senserva AI Opinion for CVE-2025-62452
A Critical CVSS 9.8 remote code execution flaw in Routing and Remote Access Service on Windows 10 1809 and Server 2019. The Critical rating sets it apart from the many High-rated RRAS bugs, though EPSS remains low at 6 percent since exploitation still depends on the RRAS role being present and reachable. For organizations running RRAS as their VPN, a 9.8 in that exact service is a direct external threat.
Do this: Patch RRAS-enabled Server 2019 systems immediately and confirm the service is absent or disabled everywhere else.
