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?
