| 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 that the user reauthenticate.

Details
Check Text (C-274868r1107313_chk)
Verify that "/etc/sudoers" has no occurrences of "NOPASSWD" with the following command:
$ sudo egrep -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 using multifactor authentication (MFA), this is a finding.
Fix Text (F-78874r1101744_fix)
Configure the operating system to not allow users to execute privileged actions without authenticating with a password.
Remove any occurrence of "NOPASSWD" found in "/etc/sudoers" file or files in the "/etc/sudoers.d" directory.
$ sudo find /etc/sudoers /etc/sudoers.d -type f -exec sed -i '/NOPASSWD/ s/^/# /g' {} \;
