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.

ℹ️ Check

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.

✔️ 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/*
