[+] Application Description :

Winlog Lite is the entry level version of the SCADA/HMI software Winlog Pro 
offered by Sielco Sistemi to allow an evaluation of the potentiality and the 
simplicity of use of the package; Winlog Lite is also a powerful and low cost
solution for creation of small supervisory applications.

Winlog Lite makes available most of development tools and functions provided by
the Winlog Pro software package, but limits the possibility to develop and to
run applications up to a max of 24 tags. Winlog Lite does not include Symbol 
Factory library and web support.

Winlog Lite can be executed both in Demo mode (without need of registration) 
and Full mode; in Demo mode, communication with external devices and sampling
of external tags automatically stops after 15 minutes (if required, it can be 
restarted manually); in Full mode communication goes on without any limit of time.

[+]Proof Of Concept  : 

After run Winlog Lite SCADA HMI SYSTEM go to Tools Menu and Application Builder
So , we can injected our Data to Application Name and Select Build Bottom 
after attach program to debugger :

9986 byte A + Pointer to next SEH record (6 byte jmp) + 
SE handler --> Non-SafeSEH Address for bypass SafeSEH Protection(0x32450A7B) + NOP + jmp ESP (0x7C86467B) + shellcode
