RHEL-07-010340 - The Red Hat Enterprise Linux operating system must be configured so that users must provide a password for privilege escalation.

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 re-authenticate.

Solution

Configure the operating system to require users to supply a password for privilege escalation.

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

Remove any occurrences of 'NOPASSWD' tags in the file.

Check the configuration of the /etc/sudoers.d/* files with the following command:
$ sudo grep -ir nopasswd /etc/sudoers.d

Remove any occurrences of 'NOPASSWD' tags in the file.
