CVE-2024-38069

Local security bypass via improper signature verification

Published Jul 9, 2024 · Updated Feb 10, 2026

Improper signature verification in Microsoft Windows Enroll Engine allows local users to bypass a security feature on affected Windows builds. Microsoft identifies the locus as the Enroll Engine and maps it to CWE-347, but does not disclose which signed data is accepted or how verification fails. Exploitation requires local low-privilege access and high-complexity conditions; success can compromise confidentiality, integrity, and availability.
