Notes:

This exploit basically implements the exploits Phineas Fisher used to pwn Hacking Team

and the Cayman Trust Bank place. It uses the Shellshock vulnerability to gain a command

execution primitive as the "nobody" user in the cgi-bin/jarrewrite.sh web-script, spawns

a trivial reverse shell using /dev/tcp.

There is a fairly trivial LPE in these that gets you root by abusing setuid dos2unix, but

implementing that is left as an exercise for the reader. I've seen a few approaches, and

would be interested in seeing yours.

There is another LPE that works only on some models which I also have removed from this.
