The CERT Vulnerability Note VU#854306 indicated that the SNMP processing
of
GetRequest, SetRequest, GetNextRequest, GetResponse, and Trap has
vulnerablities.
These weaknesses include "denial-of-service conditions, format string
vulnerabilities, and buffer overflows."  In addition, "some
vulnerabilities do not require the request message to use the correct
SNMP community string".

Which means, the SNMP service can be used to compromise OS/400.

IBM responded with:  "Based upon the results of running the test suites
we have determined that our version of SNMP shipped with AIX is NOT
vulnerable."

If Dr. Frank's hypothesis is right, IBM SNMP implementation is probably
the same for AIX as it is for OS/400.  Which makes my worries go away -
- Right??????

I know that SNMP is used regularly on internal networks.  Some people
are even using it to drive their AS/400 printers.  A couple of customers
want to remotely manage their equipment, using VPN connections on the
Internet.  SNMP could be the right tool, but only if internal hackers
can be kept out!  With the CERT notification,  and in general, is a
properly configured AS/400 susceptible to SNMP attacks?
