A vulnerability was discovered where the restrictions caused by $cfg['Servers'][$i]['AllowNoPassword'] = false are bypassed under certain PHP versions. This can allow the login of users who have no password set even if the administrator has set $cfg['Servers'][$i]['AllowNoPassword'] to false (which is also the default).
This behavior depends on the PHP version used (it seems PHP 5 is affected, while PHP 7.0 is not).
We consider this vulnerability to be of moderate severity.
Set a password for all users.
