Exploiting a simple TCP connection...

Just wondering...

In MetaSploit, there are many exploits for specific programs e.g. Acrobat Reader, etc. and for services (SSH, FTP etc.); but is it possible to get a shell on a computer with which you have established a direct TCP connection?

This could have many uses such as social engineering with file transfers, IRC direct connections etc. etc.

The only problem i can see is that although a TCP connection has been established, the program on the other end may or may not allow/support remote code execution, making it impossible to exploit until an actual exploit has been found.

Any thoughts/ideas as to how something like this could be accomplished?

If you take possibility of an actual exploit out, I guess there is nothing much you can do. I'd say social engineering is the key !

Just my two cents, I hope someone better than me at this will have a more interesting answer ;)
