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 the user reauthenticate.

Check Content

Verify the "/etc/sudoers" file has no occurrences of "!authenticate" with the following command: 
 
$ sudo egrep -iR '!authenticate' /etc/sudoers /etc/sudoers.d/
 
If any occurrences of "!authenticate" return from the command, this is a finding.

Fix Text

Remove any occurrence of "!authenticate" found in "/etc/sudoers" file or files in the "/etc/sudoers.d" directory.
