HTTP Proxy Open gopher:// Request Relaying

This script is Copyright (C) 2003-2014 Tenable Network Security, Inc.

Synopsis :

The HTTP proxy accepts gopher:// requests.

Description :

Gopher is an old network protocol which predates HTTP and is nearly
unused today. As a result, gopher-compatible software is generally
less audited and more likely to contain security bugs than others.

By making gopher requests, an attacker may evade your firewall settings,
by making connections to port 70, or may even exploit arcane flaws in
this protocol to gain more privileges on this host (see the attached CVE
id for such an example).

Solution :

Reconfigure your proxy so that it refuses gopher requests.

Risk factor :


Family: Firewalls

Nessus Plugin ID: 11305 ()

Bugtraq ID: 4930
