Ensure re-authentication for privilege escalation is not disabled globally

СредњаНиво 1Аутоматскаlinux

Опис

By default sudo re-authenticates the invoking user before escalating privileges. The !authenticate tag, where present in the sudoers configuration, disables that re- authentication; without it, sudo prompts the user to confirm their identity before running elevated commands.

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Configure the operating system to require users to reauthenticate for privilege escalation. Based on the outcome of the audit procedure, use visudo -f <PATH TO FILE> to edit the relevant sudoers file. Remove any occurrences of !authenticate tags in the file(s). Because sudo applies the last matching definition, ensure no later-parsed file in /etc/sudoers.d re-introduces an !authenticate tag; see this section's overview for how the sudoers files combine.
