TOSS 5 must require users to provide a password for privilege escalation.

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.

Verify "/etc/sudoers" has no occurrences of "NOPASSWD" using the following command:

$ sudo grep -ri nopasswd /etc/sudoers /etc/sudoers.d/*

If any occurrences of "NOPASSWD" are returned and this is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.

Configure TOSS 5 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 sed -i '/NOPASSWD/ s/^/# /g' /etc/sudoers /etc/sudoers.d/*
