This Metasploit 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 Metasploit 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.
9ea26d2b6cb47fda41b9580e28eab68d2c736833da3e4ee9317fb28219b79c3fiDefense Security Advisory 05.03.11 - Remote exploitation of a memory corruption vulnerability in Tom Sawyer Software's GET Extension Factory could allow an attacker to execute arbitrary code with the privileges of the affected user. The vulnerability exists within the way that Internet Explorer instantiates GET Extension Factory COM objects, which is not intended to be created inside of the browser. The object does not initialize properly, and this leads to a memory corruption vulnerability that an attacker can exploit to execute arbitrary code. iDefense has confirmed Tom Sawyer's Default GET Extension Factory 5.5.2.237, tsgetxu71ex552.dll and tsgetx71ex552.dll to be vulnerable. VMWare VirtualCenter 2.5 Update 6, VirtualCenter 2.5 Update 6a is vulnerable.
