Summary
This rule detects potential vulnerabilities in Active Directory Certificate Services (ADCS) related to certificate templates that allow potentially risky permission assignments to certificate subjects. Specifically, it looks for the configuration settings of certificate templates that include the flag `CT_FLAG_ENROLLEE_SUPPLIES_SUBJECT`, which could grant higher access permissions than intended to users requesting certificates. This is essential for mitigating risks associated with privilege escalation and unauthorized access through weak or misconfigured certificate templates. The detection leverages Windows Security Event ID 4898, which is triggered when a certificate services template is loaded, and ID 4899, triggered when the template is updated. By monitoring these events, organizations can identify potentially malicious or improper configurations that could lead to exploitation.
