Indeed,

Which is why there are advisories all the time
about such problems in cable modems and routers
and switches.  But Netgear RPXXX series routers
etc... do not have the admin interface enabled
on anything but the LAN, nor do most have SNMP
at all.  Linksys routers are the same by default,
limited to the LAN for ocnfiguration connections,
althought they have other problems yet to be
addressed.  For home DSL/Cable routers the biggest
problem I see at the moment that is still a general
problem is that many come with default logins
and default SNMP communities.
