    Cheers,
    
    I found a Timbukto Pro (Remote Control NT Tool) vulnerability.
    
    Concerned product : Timbuktu Pro 2.0b650 on Windows NT 4.0 until sp5
    
    "Exploit" is :
    
    - Connect and disconnect on port TCP/407 to make port TCP/1417 listening
    - Connect on port TCP/1417 with a simple telnet.
    - Disconnect from TCP/1417 (no data exchange).
    
    Authentication protocol waits indefinitely.
    
    This brings Timbukto Remote Control Denial-of-Service on control. Physical
    contact is then needed to restart it.
    
    Solution to get back operational:
    	- Kill timbuktu process (using pslist/pskill for example)
    	- Stop Timbuktu services
    	- Start them again.
    
    Patches:
    	Not yet
    
    Netopia is now aware of this.
    
    Best regards
