The only apparent and widely exploitable way to do this is to replace the firmware. While not trivial, this is doable. Existing firmware already supports sending SNMP packets, we only need change the data and type.
Assuming of course that the download isn't checked for a crypt sig. Of course, that means that somewhere in the running code, however disguised, is a key, and to change keys you have to follow a trail of firmware updates... you obviously can't depend on being able to access a "known site" for "known good" sigs... -- Charles C.
