# 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.
