<bug_description>Port tcp/3128 is the default port for Squid proxy servers. If an attacker can connect to the port, start an HTTP request and get an HTTP reply, he can be very sure that there is a web proxy available.</bug_description>
<bug_solution>Reconfigure the remote Squid proxy so that it only accepts requests coming from inside your network.</bug_solution>
