Telnet Service Detection

This script is Copyright (C) 1999-2014 Tenable Network Security, Inc.


Synopsis :

Telnet service appears to be running on the remote system.

Description :

The Telnet service is running. This service is dangerous in
the sense that it is not ciphered - that is, everyone can
sniff the data that passes between the telnet client and
the telnet server. This includes logins and passwords.

Solution :

If you are running a Unix-type system, OpenSSH can be used
instead of telnet. For Unix systems, you can comment out the
'telnet' line in /etc/inetd.conf. For Unix systems which use
xinetd, you will need to modify the telnet services file in the
/etc/xinetd.d folder. After making any changes to xinetd or
inetd configuration files, you must restart the service in order
for the changes to take affect.

In addition, many different router and switch manufacturers
support SSH as a telnet replacement. You should contact your vendor
for a solution which uses an encrypted session.

Risk factor :

None
