Overview
Affected versions of this package are vulnerable to Insufficient Granularity of Access Control via the lack of uniqueness enforcement on the krbCanonicalName attribute. An attacker can gain full administrative privileges across the domain by crafting a principal with the same canonical name as the domain administrator and obtaining a Kerberos service ticket containing PAC data. This enables unrestricted access to sensitive systems and data, including user management, policy manipulation, and credential extraction.
