Verify the operating system is not be configured to bypass password requirements for privilege escalation.

Check the configuration of the "/etc/pam.d/sudo" file with the following command:

$ sudo grep pam_succeed_if /etc/pam.d/sudo

If any occurrences of "pam_succeed_if" are returned from the command, this is a finding.

Fix

Configure the operating system to require users to supply a password for privilege escalation.

Check the configuration of the "/etc/ pam.d/sudo" file with the following command:

$ sudo vi /etc/pam.d/sudo

Remove any occurrences of "pam_succeed_if" in the file.
