Console access is only the front access.. (Standard commands, and a few things developers left behind.)
On the other hand, it is technically possible to gain control of the engine to do a whole lot more.. (Spawning mobs, etc)
Now, I'm not quite sure about how poorly the game is written.. (Although Nexon's notorious for writing really bad serverside code.)
But considering how you're able to manipulate various clientside aspects and have it reflect on the server.. I wouldn't put it past me to say that there aren't ways to generate items.
