Description
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.

ℹ️ Check
Verify RHEL 10 "/etc/sudoers" has no occurrences of "!authenticate" with the following command:
$ sudo grep -ir '!authenticate' /etc/sudoers /etc/sudoers.d/
If any occurrences of "!authenticate" are returned, this is a finding.
✔️ Fix
Configure RHEL 10 to not allow users to execute privileged actions without authenticating.
Remove any occurrence of "!authenticate" found in the "/etc/sudoers" file or files in the "/etc/sudoers.d" directory:
$ sudo sed -i '/\!authenticate/ s/^/# /g' /etc/sudoers /etc/sudoers.d/*
