'Name' => 'MicroP 0.1.1.1600 (MPPL File) Stack Buffer Overflow',
'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.
