  			'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.
