Title

RHEL 10 must not have accounts configured with blank or null passwords.

Control

Verify RHEL 10 prohibits null or blank passwords with the following command: $ sudo awk -F: '!$2 {print $1}' /etc/shadow If the command returns any results, this is a finding.

Discussion

If an account has an empty password, anyone could log in and run commands with the privileges of that account. Accounts with empty passwords should never be used in operational environments.
