Technical details
The vulnerability stems from incorrect permission assignment (CWE-732) in the Network Authentication Service where an attacker-controlled file path is not properly validated before performing ownership changes. Attack requires local authentication and user interaction is not needed. A local authenticated attacker can change the ownership of arbitrary files, potentially gaining elevated privileges or compromising system integrity.
