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 "NOPASSWD" or "!authenticate" by using the following command:  
  
     $ sudo grep -Ei '(nopasswd|!authenticate)' /etc/sudoers /etc/sudoers.d/* 
  
If any occurrences of "NOPASSWD" or "!authenticate" return from the command, this is a finding.

Fix Text

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