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 RHEL 9 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

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

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