Synopsis

The remote host is running a version of macOS that is affected by a root authentication bypass vulnerability.

Description

The remote host is running a version of macOS that has a root authentication bypass vulnerability. A local attacker or a remote attacker with credentials for a standard user account has the ability to blank out the root account password. This can allow an attacker to escalate privileges to root and execute commands and read files as a system administrator.

Solution

Enable the root account and set a strong root account password.
