Discussion

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.

Check Content

Verify the operating system requires users to supply a password for privilege escalation.

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

$ sudo grep -ir nopasswd /etc/sudoers /etc/sudoers.d

If any occurrences of "NOPASSWD" are returned from the command and have not been documented with the Information System Security Officer (ISSO) as an organizationally defined administrative group utilizing MFA, this is a finding.

Fix Text

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.
