<bug_affected>Gnutella and BearShare peer-to-peer sharing software</bug_affected>
<bug_vulnerability_class>Configuration</bug_vulnerability_class>
<bug_description>Gnutella is a well-known peer-to-peer software for sharing files. An open port tcp/6346, the returning banner and a response to a Gnutella protocol request indicate the existence. Gnutella may be illegal in the environment.</bug_description>
<bug_solution>Disable Gnutella if not allowed nor needed. If Gnutella should run then filter incoming traffic on port tcp/6346 to prevent unwanted access to the web interface.</bug_solution>
