Check
Verify Amazon Linux 2023 is not configured to bypass password requirements for privilege escalation with the following command:
$ sudo grep pam_succeed_if /etc/pam.d/sudo
If any occurrences of "pam_succeed_if" are returned, this is a finding.
Fix
Configure Amazon Linux 2023 to require users to supply a password for privilege escalation.
Remove any occurrences of "pam_succeed_if " in the "/etc/pam.d/sudo" file.
