Senserva AI Opinion for CVE-2025-47981

A Critical Severity (CVSS 9.8) Remote Code Execution flaw in SPNEGO Extended Negotiation (NEGOEX), the mechanism Windows uses to negotiate authentication before a user is ever authenticated. Pre-authentication network-reachable bugs in this layer are the wormable kind that need no credentials and no user action. Windows 10 1809 and Windows Server 2019 are affected, and while EPSS is 22% and no exploitation is confirmed, the class alone justifies urgency.

Do this: Patch Server 2019 systems exposed to untrusted networks first, and segment or firewall any that must wait.

AI-generated from public data, 2026-07-07. Verify against the vendor advisory before acting.
