Senserva AI Opinion for CVE-2025-33071
This is a use-after-free style remote code execution flaw in the KDC Proxy Service (KPSSVC), the component that tunnels Kerberos authentication over HTTPS for remote clients and Windows Server 2019 and 2022 acting as KDC proxy servers are exposed. It carries an 82 percent EPSS score with Severity High (CVSS 8.8), meaning attack code is likely to appear even though it is not yet in CISA KEV or tied to ransomware. KDC proxy servers are often internet-facing to support remote workers, which widens the attack surface for an unauthenticated remote attacker.
Do this: Apply the Microsoft patch to all Windows Server 2019 and 2022 systems running KPSSVC and prioritize any internet-facing KDC proxy endpoints first.
