RE: Routes that are susceptible to SNMP

["Rob Shein" <shoten () starpower net>]

Your question had some ambiguity, so I present you with "if, then, else"
answers:

By "susceptible to snmp with a community string of public," is that
read-write access or read only?  And if read-only, have you seen if you get
read-write by using "private" as a community string?  Either way it's bad,
but at least with read-only you can't start CHANGING things on them.

By "how dangerous this is," do you mean the fact that snmp is available to
the outside world with a default community string, or that people can look
at the ARP table?  The ARP table info is a tad useful to an attacker in
conjunction with other things, but the openness of the router is the real
nightmare, and obviously it becomes like "Nightmare on Ascend Street" if you
have read-write access from the internet via defaults.
