Motorola SBV5120 Exploit

[Cristian Stoica <security () netcms biz>]

Hi,

   I've did some tests( DoS ) with cable modems and I've notice the 
following problem:
   running nmap on the management ip address of the cable modem 
resulted into a response of the modem of about 3-5 s not ms and the 
network behind the modem was unable to use the internet.
   I've used no special options for nmap, simply running nmap 
ip_address had that result.
   I've tested with Scientific Atlanta, Thomson, RCA modems and none 
reacted that way.
   I think that this is an easy DoS for Motorola cable modems, that can 
be started from inside the network also aginst the ip 192.168.100.1 ( 
the standard management ip address for docsis cable modems ).
   Anyone else had this problem ?
   Beside restricting access to the vlan with the management address is 
there any other things that can be done ?

Best regards,
Cristian Stoica
