      The most interesting part of the SME hack is upgrading from a crappy netcat to a full screen session [25:12]. Handy!https://www.youtube.com/watch?v=oTbI74ti0yY#t=25m12 …

      so basically that's just shell code execution from a python process web server?

      No, it's just a netcat shell. The point is he uses python to spawn a pty, fixes up the local terminal, then gets a screen going.

      So he goes from a barebones broken non-interactive shell to a fully working screen session that can run vim.

      And is this a exploit on a live website? Or internal test server?

      This was a exploit on a live server (blackhat), but the tty trick is unrelated to the exploit and very useful in other contexts.

      E.g. shitty serial consoles on embedded devices, or rescue shells on systems you own.
