CVE-2024-49019 is an elevation of privilege vulnerability in Active Directory Certificate Services (AD CS). The flaw affects unpatched certificate authority deployments that issue certificates from built-in default version 1 certificate templates. An authenticated attacker with certificate enrollment rights can abuse these templates by crafting certificate signing requests that inject arbitrary application policies, causing the issued certificate to contain capabilities beyond the template’s intended Extended Key Usage restrictions. Reported exposure is increased when version 1 templates allow the subject name to be supplied in the request and grant broad Enroll permissions. In practice, this enables abuse of AD CS trust to obtain certificates usable for privileged authentication and impersonation within Active Directory, and the issue is associated with the ESC15 abuse path, also referred to as EKUwu.
