X Server Detection

This script is Copyright (C) 2005-2013 Tenable Network Security, Inc.


Synopsis :

An X11 server is listening on the remote host

Description :

The remote host is running an X11 server. X11 is a client-server
protocol that can be used to display graphical applications running on
a given host on a remote client.

Since the X11 traffic is not ciphered, it is possible for an attacker
to eavesdrop on the connection.

Solution :

Restrict access to this port. If the X11 client/server facility is not
used, disable TCP support in X11 entirely (-nolisten tcp).

Risk factor :

Low / CVSS Base Score : 2.6
(CVSS2#AV:N/AC:H/Au:N/C:P/I:N/A:N)
