Pastebin challenge seems to be currently unsolvable with the intented way.
No wonder I couldn't solve that today, even though I have an idea of what to do.
It's also a bit strange that one challenge is designed in a way to give you a free code injection vuln...so you can easily get a limited shell on the server. You are limited by the user, but that's no guarantee for the long term!
