Title
RHEL 9 must require users to provide a password for privilege escalation. (Cat II impact)
Discussion
Without reauthentication, users may access resources or perform tasks for which they do not have authorization. When operating systems provide the capability to escalate a functional capability, it is critical that the user reauthenticate.

Check Content
Verify that "/etc/sudoers" has no occurrences of "NOPASSWD" with the following command: $ sudo grep -ri nopasswd /etc/sudoers /etc/sudoers.d/* If any occurrences of "NOPASSWD" are returned, this is a finding.
Fix Text
Configure RHEL 9 to not allow users to execute privileged actions without authenticating with a password. Remove any occurrence of "NOPASSWD" found in "/etc/sudoers" file or files in the "/etc/sudoers.d" directory. $ sudo sed -i '/NOPASSWD/ s/^/# /g' /etc/sudoers /etc/sudoers.d/*
