Summary
An information exposure flaw in openstack-tripleo-heat-templates allows an external user to discover the internal IP or hostname. An attacker could exploit this by checking the www_authenticate_uri parameter (which is visible to all end users) in configuration files. This would give sensitive information which may aid in additional system exploitation. This flaw affects openstack-tripleo-heat-templates versions prior to 11.6.1.
