Senserva AI Opinion for CVE-2025-59287
The exploit target here is the patching infrastructure itself: WSUS on Windows Server 2019 and 2022 has a Critical CVSS 9.8 remote code execution flaw with a 100% EPSS score. A compromised WSUS server can push malicious content to every client it manages, making this a whole-estate risk rather than a single-server one.
Do this: Patch WSUS servers immediately and restrict inbound access to the WSUS service to only what clients require.
