KB5052072 is a High security update for Windows Server 2008, released 2025-02-11. It closes 19 CVEs with a maximum CVSS of 8.8. At least one of them is actively exploited (CISA KEV), so this is a deploy-first update. The most likely of them to be attacked is CVE-2025-21352, which FIRST.org rates at 40% probability of exploitation in the next 30 days.
Our data comes from Microsoft, CISA and other public sources, and it can be wrong or out of date. If you are unsure, check the linked source before you act, and tell us when we are wrong so we can fix it.
Update summary
Fixes 19 CVEs. At least one is actively exploited (CISA KEV). Most severe CVSS 8.8 (High). EPSS exploit probability up to 9.4%. Among the top half of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Windows Server 2008 for 32-bit Systems Service Pack 2 has shipped since this one: KB5073697 (2026-01-13). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
KB5052072 is a February 2025 update for Windows 10 1809 and Windows Server 2019, closing 19 CVEs with a High, CVSS 8.8 top severity, but a comparatively low 9 percent EPSS score, and a CISA KEV listing among the fixes. The lower EPSS alongside an active-exploitation confirmation is a reminder that EPSS predicts future exploitation likelihood and can lag behind a flaw that's already been used, so treat the KEV entry as the higher-priority signal here. This overlaps CVE content with the larger February 2025 builds covered elsewhere.
Do this: Prioritize KB5052072 based on its CISA KEV listing rather than its comparatively low 9 percent EPSS score.
