Discussion

If the "sudoers" file is not configured correctly, any user defined on the system can initiate privileged actions on the target system.

Check Content

Verify the operating system restricts privilege elevation to authorized personnel with the following command:

$ sudo grep -iwR 'ALL' /etc/sudoers /etc/sudoers.d/ | grep -v '#'

If the either of the following entries are returned, this is a finding:
ALL     ALL=(ALL) ALL
ALL     ALL=(ALL:ALL) ALL

Fix Text

Configure the operating system to restrict privilege elevation to authorized personnel.

Remove the following entries from the /etc/sudoers file or any configuration file under /etc/sudoers.d/:

ALL     ALL=(ALL) ALL
ALL     ALL=(ALL:ALL) ALL
