Date: Fri, 8 Feb 2008 16:15:58 -0500 From: "Erik Harrison" <eharrison@...il.com> To: reepex <reepex@...il.com> Cc: full-disclosure@...ts.grok.org.uk Subject: Re: ASUS Eee PC rooted out of the box Who cares? Of all the information posted on this list each and every day, you choose this to whine about? Is there no value in knowing that this particular system has a remote-root exploit out of the box? I find this information more valuable than the thousands of SQL injection advisories for tiny software apps who have only ever been downloaded from SF 16 times. Chances are, this is likely more of a real problem that I'm to encounter in my life. The claim that this is 'media hyped' is a bit ridiculous. If this were written for that audience, we probably wouldn't be reading raw process lists or metasploit output. Though I would certainly enjoy seeing this republished in some major newspaper tomorrow, if only to force/embarrass the vendor into patching the default image for these machines when they're shipped - like they should be doing anyway. Is there anything wrong with that? So, thank you for posting this advisory. While technically it's no new information, not a new exploit, I appreciate knowing that I can visit my friends homes and root their boxes while they order pizza wirelessly on their couch.
