Issue is just with the default configuration, but can be easily reconfigured
to listen on localhost only. sphinxsearch will not be started automatically
and an admin needs first to create anyway a /etc/sphinxsearch/sphinx.conf
starting from a sample.
sphinxsearch should ideally update the defaults in sample configs to bind
listeners to localhost.
This is not treated as a vulnerability, subject to design choices for deployment
