Title
TOSS must require users to provide a password for privilege escalation. (Cat II impact)
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 reauthenticate.
Check Content
Verify that "/etc/sudoers" has no occurrences of "NOPASSWD." Check that the "/etc/sudoers" file has no occurrences of "NOPASSWD" by running the following command: $ sudo grep -i nopasswd /etc/sudoers /etc/sudoers.d/* %admin ALL=(ALL) NOPASSWD: ALL 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 multifactor authentication (MFA), this is a finding.
