Technical details

The BuildDisk utility in NeXTSTEP versions prior to 2.0 contains a privilege escalation vulnerability. The application does not implement an authentication check or password prompt when executed, despite performing actions that require root-level permissions. A local attacker with standard user access can execute the BuildDisk program to gain unauthorized root privileges. This issue was addressed in NeXTSTEP version 2.0.
