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