Risk summary
Senserva AI Opinion for CVE-2024-38217
The more severe of the exploited Mark of the Web bypasses, rated Critical Severity at CVSS 9.8 with a 71% EPSS and a CISA KEV entry from September 2024. Attackers abuse it to deliver files to Windows 10 1809 and Windows Server 2019 machines without the downloaded-file warnings and policy checks that normally apply. Because the entire smart-app-control and screening chain keys off that web mark, this single bypass undermines several defensive layers at once.
Do this: Confirm the September 2024 update is deployed to every 1809 and Server 2019 endpoint, then rely on application control policies rather than download prompts for interim protection.
