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 that "/etc/sudoers" has no occurrences of "!authenticate."

Check that the "/etc/sudoers" file has no occurrences of "!authenticate" by running the following command:

$ sudo grep -i 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.
