I'll answer your questions individually.
First thing to understand is that not all vulnerabilities have a
corresponding "publicly available" exploit, yes the 0hday still
exists.
<<where is the expoit information?>>
As i said before, not all known vulnerabilities have publicly
available exploit code. I'd suggest getting kinky with Metasploit or a
subscription to Canvas/that other one i cant think of right now. If
they are publicly available, those crazy french peeps over at k-otik
may have it (http://www.frsirt.com/english/)
<<What is the vulnerability?>>
if your on the pen-test mailing list, i'm gathering your a sexurity
conslutant and have some idea of where security vulnerabilities are
announced, if not, google/securityfocus.com/apple.com/security &
full-disclosure mailing list.
<<Do exploits exist? >>
oh yes, they do and don't let some vendor tell you otherwise.
<<Can you test if you are vulnerability?>>
This is the main issue currently splitting the security consultancy
industry in half at the moment, on the one hand you have people who
call themselves "pen-testers" but only are able to rely on automated
tools and scripts to test (therefore should be known as vulnerability
assessment consultants) and then you have consultants who are able to
read a vulnerability statement and have a understanding of how to look
for the issue and perform a test.
Here, very roughly, is how you could test:
find a vulnerability that you know you have the skill set to test for,
hmmm in this case i'll pick the iTunes issue found by those lovely
people at iDefense
http://www.idefense.com/application/poi/display?id=180&type=vulnerabilities
* i'm using this one as an example, yes you need the person to click
and listen to the playlist, but hell social engineering is all part of
the game, so apologies to all that its not a 100% remote issue *
So the issue is that iTunes gets it's knickers in a knot when parsing
playlist files which may contain really long URL file entries. Well
this is a simple classic issue here, well documented and armed with
your copy of the shellcoders handbook, easy to create a test for.
[playlist]
numberofentries=1
File1=http://[P x 3333] 2233
Length1=-1
Version=2
Save that file and somehow get a person on the box to open it (pretty
easy, tell them your doing a test for the IT department and this is to
check to see if the microphone is enabled, as if it is a virus could
record all office noise)
iTunes will crash and if you took steps to actually exploit this
crash, you may end up with code being executed.
<<Apple doesn't follow Full-Disclourse>>
And i'm 1000% supportive of this process as is
Microsoft/Oracle/Sun/Sybase etc, why should they report detailed
information about the security hole? They list the issue and also if
it was fixed and how to go about fixing it using a supplied patch or
method.
Here's hoping all the questions raised have been answered?
