Senserva AI Opinion for CVE-2025-62571

Windows Installer runs with SYSTEM privileges to service MSI packages, and this High Severity (CVSS 8.8) flaw lets a local user hijack that to elevate on Windows 10 1809 and Windows Server 2019. Installer escalations appeal to attackers because the service exists on every machine and repair operations can be triggered by unprivileged users. EPSS is 5 percent with no confirmed exploitation.

Do this: Patch shared-use systems first: Server 2019 terminal servers and Windows 10 1809 kiosks where untrusted users hold local sessions.
