Senserva AI Opinion for CVE-2025-49735

The Windows KDC Proxy service on Server 2019 and 2022 has a High Severity CVSS 8.8 remote code execution flaw, and its 82 percent EPSS score is among the highest on this page. KDC Proxy exists specifically to expose Kerberos authentication over HTTPS to the internet for remote access scenarios like RD Gateway and DirectAccess, so vulnerable instances are often externally reachable by design. High EPSS plus intentional internet exposure is the combination that turns into KEV entries.

Do this: Identify every server running the KDC Proxy service, especially internet-facing RD Gateway or DirectAccess hosts, and patch those first today.
