Information

Without re-authentication, 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.

Solution

Configure the operating system to require users to reauthenticate for privilege escalation.

Check the configuration of the '/etc/sudoers' file with the following command:

# visudo
Remove any occurrences of '!authenticate' tags in the file.

Check the configuration of the '/etc/sudoers.d/*' files with the following command:

# grep -i authenticate /etc/sudoers /etc/sudoers.d/*
Remove any occurrences of '!authenticate' tags in the file(s).
