Description

This module exploits a remote code execution vulnerability in the tsgetx71ex553.dll
ActiveX control installed with Tom Sawyer GET Extension Factory due to an incorrect
initialization under Internet Explorer.

While the Tom Sawyer GET Extension Factory is installed with some versions of VMware
Infrastructure Client, this module has been tested only with the versions installed
with Embarcadero Technologies ER/Studio XE2 / Embarcadero Studio Portal 1.6. The ActiveX
control tested is tsgetx71ex553.dll, version 5.5.3.238.

This module achieves DEP and ASLR bypass using the well known msvcr71.dll rop chain. The
dll is installed by default with the Embarcadero software, and loaded by the targeted
ActiveX.
