Title

RHEL 10 must require users to reauthenticate for privilege escalation.

Control

Verify RHEL 10 "/etc/sudoers" has no occurrences of "!authenticate" with the following command: $ sudo grep -ir '!authenticate' /etc/sudoers /etc/sudoers.d/ If any occurrences of "!authenticate" are returned, this is a finding.

Discussion

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.

Fix

Configure RHEL 10 to not allow users to execute privileged actions without authenticating. Remove any occurrence of "!authenticate" found in the "/etc/sudoers" file or files in the "/etc/sudoers.d" directory: $ sudo sed -i '/\!authenticate/ s/^/# /g' /etc/sudoers /etc/sudoers.d/*
