Dear Eero I appreciate the help but the question is not how to secure/firewall the server. The question is why OpenVAS is telling that is possible to connect as admin:admin and I cannot verify the problem.
What is tested? How can I reproduce the problem? I checked the configuration and the admin password is *not* admin. Could it be that the plugin is reporting a false positive?
