It appears more than one vendor shared the same SNMP library (or SNMP programmer). Folks have sent me evidence at least two other vendor's equipment has similar responses to the same SNMP community string ILMI.
However, there are other non-related SNMP issues. Many SNMP implementations included the default community strings "public" and "private". If the operator doesn't change them, the defaults may still work. The other common SNMP implementation issue is if no community string is specified, the SNMP agent accepts any community string.
If you are checking your network, I'd suggest checking for all three possibilities.
IMHO, if no communities are supplied, the SNMP daemon should not respond at all.
While I agree that "public" and "private" are "wellknowns," in most implementations, they at least show up in the code. Cisco chose to hide this one where it would not show up in the code. That IMHO is a very bad thing and does bad things to my confidence level in Cisco.
Please, stop the damn FUD, how do you know it wasn't accidentally left in by a programmer doing debugging? I bet you assume all buffer overflows are purposely put in also, eh? Sure. I expect it to cut back on your confidence in Cisco IOS, but also, what's this noise about code? Do you happen to have a hold on IOS source code or something that you personally audit?
