Systems Affected
Systems running versions of telnetd derived from BSD source.
How many of us here run anything less than SSH and even allow telnetd to live on any of our hosts?
telnetd is not inherently bad. It is a tool that is lacking the session encryption and strong authentication features of SSH, but is still useful in some cases. Like any tool it can be used poorly, but that is not the fault of the tool.
For example, when traveling, I can log in securely from any random Internet cafe using OPIE or S/Key one-time passwords via telnet. SSH requires that you trust your local machine, and OPIE assumes that you don't.

You may not expose your password to get into your network but, you do expose everything else that happens on the connection, including the passwords to devices that do not use/support OPIE or S/Key authentication. You can run an SSH client in a java applet in nearly any browser. If some devices on your network don't support ssh, ssh into something that does and from there, telnet to the devices that don't. --- John Fraizer EnterZone, Inc
