Re: HP Photosmart vulnerabilities

[Joshua Levitsky <jlevitsk () joshie com>]

Dude SNMP can be used by their software to query the printer for toner  
levels or that it is online. You tell me what exactly you are getting  
from a printer like that via SNMP besides print job status and ink  
levels? And you are a stranger in my home on my network? I'd have the  
po-po beating you like Rodney King before you had to worry about what  
is on my printer.

If I really have to explain to you why you don't need SSL to configure  
a home / home office printer that costs $200 and is intended for a  
personal private network then really there is no point in explaining  
it. Security is meant to reduce risk. When you explain to me what the  
risk is then you can state what the benefit of disabling SNMP and  
adding SSL would be to reduce that risk. There... I just wasted 10  
seconds of my life explaining it.
