[HooToo] Multiple unauth exploits for TripMate series.

[DePierre]

Three modules to exploit vulnerabilities in HooToo TripMate series:

• Unauthenticated Remote Code Execution in /sysfirm.csp
• Multiple Instances of Unauthenticated Operating System Command Injection in open_forwarding
• Unauthenticated Arbitrary File Upload

I am not entirely sure that I am using shell() correctly so feel free to tell me what to change in those modules :)

They are still unpatched as of today, as far as I can tell, despite attempting to report them since October, 2017.

Thanks for the contribution! Could you please separate this PR to multiple PRs so we can analyze all exploits separately?

Hi @lucyoa, I would usually comply with this kind of requests but I really think that it is not necessary here.

All 3 exploits are simple to understand (1 command execution, 1 command injection and 1 path traversal) and because they are already in a file of their own, less than 100 LoC each, you can review them one after the other.
