'Description' => %q{

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.
