The answer is: quite probably. A lot of old systems get retrofitted with additional features/terminals/addons on top to make them "more modern" and as a result end up being connected to the internet. A great presentation on this (and many other things) here: [VIDEO]

Defcon 20 - Dan Tentler - "Drinking from the caffeine firehose we know as shodan" [VIDEO] Warning - watching this may readjust your faith in humanity. Telnet is just the tip of the iceberg. edit: (15:42) "Econolite [stoplights] listening on telnet. There are intersections [with] stoplights; you can telnet into them and put them in 'test mode'[sic], and the warning says, 'Don't do this, you could kill people!'"

It's both amazing and scary that this kind of vulnerability is fairly common. Check out this great talk given at Defcon ( [VIDEO] ) to get an idea of the magnitude. These are systems that do not require any kind of tampering or credentials. Most times credentials are given to you in a prompt!
