    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.
