Searches for the existence of Telnet Detailed Explanation for this Vulnerability Assessment 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.
