1.269 RHEL-10-600455

Information

RHEL 10 must not allow blank or null passwords.

GROUP ID: V-281200RULE ID: SV-281200r1166552

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

Solution

Configure RHEL 10 to prohibit the use of null passwords.

If PAM is managed with "authselect", use the following command to remove instances of "nullok":

$ sudo authselect enable-feature without-nullok

Otherwise, remove any instances of the "nullok" option in the "/etc/pam.d/password-auth" and "/etc/pam.d/system-auth" files to prevent logins with empty passwords.

Note: Manual changes to the listed file may be overwritten by the "authselect" program.
