This Metasploit module exploits a lack of authentication and authorization on the InduSoft Web Studio Remote Agent, that allows a remote attacker to write arbitrary files to the filesystem, by abusing the functions provided by the software. The module uses uses the Windows Management Instrumentation service to execute an arbitrary payload on vulnerable installations of InduSoft Web Studio on Windows pre Vista. It has been successfully tested on InduSoft Web Studio 6.1 SP6 over Windows XP SP3 and Windows 2003 SP2.

Zero Day Initiative Advisory 11-330 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Indusoft Web Studio. Authentication is not required to exploit this vulnerability. The flaw exists within the Remote Agent component (CEServer.exe) which listens by default on TCP port 4322. When handling incoming requests the process fails to perform any type of authentication. Many available operations allow direct manipulation and creation of files on disk, loading of arbitrary DLLs and process control. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the User.
