Senserva AI Opinion for CVE-2025-29957

Windows Deployment Services, used for network-based OS imaging and deployment, can be knocked offline by this High 8.8 flaw with a 58 percent EPSS score on Windows 10 1809 and Server 2019. An outage here mainly disrupts imaging and provisioning workflows rather than exposing data, so the operational impact depends heavily on whether an organization still relies on WDS for deployment. It is not confirmed exploited or tied to ransomware.

Do this: Patch any server still running Windows Deployment Services, and consider whether WDS needs to stay network-exposed if imaging season is over.

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