Without reauthentication, users may access resources or perform tasks for which they do not have authorization.

Check

Verify Amazon Linux 2023 requires users to provide a password for privilege escalation.

Ensure that "/etc/sudoers" has no occurrences of "NOPASSWD" with the following command:

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

If any occurrences of "NOPASSWD" are returned, this is a finding.

Fix

Configure Amazon Linux 2023 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/*
