Type:
Access Validation Error

Release Date:
January 29, 2002

Product / Vendor:
HP AdvanceStack 10Base-T Switching Hubs combine economical 10Base-T
functionality with the performance of switching. Each switching hub

A problem with the HP switch allows some users to change
configuration of the switch. A bug introduced in the HP AdvanceStack

And a week passes and there is no response from HP SECURITY RESPONSE TEAM.
I send a mail and i say them that the time passes over and
if they do not publish a patch i will publish the hole in the security
mailing lists. Upon this, the opposite site understands this mail as a
threat with no meaning.And responds me with nonsense style. with words such;
we are 50 billion dollared company...etc... (I could not find the mail that
i have written about "4 day time" in my mail archieve,so i could not paste it here)

Hi Tamer,

I'm sorry to see the threatening tone in your message.

We did reply, and you are making the assumption that your
issue is the only one we have to work on, and that it is
the most important.

Regardless, we do not respond to threats of publishing
exploits, and we do not give out advance patch code unless
we need it to be beta tested, which is rare. We work on the
issues based on their severity in relation to the other issues,
and in most cases publish an HP Security Bulletin when the
tested solution is ready for customers to use.

Let me be very candid here, you are not the first to assume
that a $50 billion corporation will drop all the other security
issues we are working on in order to work on yours because
you threaten to publish. It has never changed the course of
our work internally; we will continue to work on the issue
until it is tested and finished.

If you decide not to publish, we would appreciate it. If you do
publish then, worst case, all that will be accomplished is
that you may cause a business somewhere to be compromised,
and they may turn to you or your company for compensation for
their financial losses. In the best case, due to September 11, 2001,
you may end up on various government agencies' "watch lists,"
and your potential career in the computer business may be
altered in ways you did not intend.

The choice is yours. We are doing our job ethically in solving the
issue. Are you doing yours to protect businesses worldwide?

Later, here is my answer to the Security Chief who
found my mail so threatening..

To: security-alert@...com

Hi Dan,

First of all I couldn't understand your threatening attitude. The
reason for my earlier mail was taking information about a subject.
And you are in a completely threatening manner. I would have
published this anouncement without waiting for your patch to be
released, if I wished... But if you are hiding behind your big
corporation and threatening me, this is really ridiculous and thought
provoking...

I won't publish this anouncement and waiting reply for your solution
or a patch.

We have published several anouncements before for companies like
Microsoft and AOL. But as big as your company's, HP, reply to this
case taught me how HP approaches deformed...

Later, the man gets more aggressive and  tries to frighten
me meaning that i could be in the blacklist of USA after 11
September just because to keep me away from publishing the
security anouncement about HP.
****************************************************

=======================SNIP==========================
From: security-alert@...com
To: ts@...urityoffice.net

Hi Tamer,

I'm sorry you perceived my previous message as threatening.
That is not the case - we are not threatening, but simply
setting expectations that we don't respond to threats of
publishing, and because the climate for security in general
has changed in the USA after September 11, 2001, we are
setting expectations for the possible results for you if
you do publish. When we deal with responsible security teams,
they do not send dated draft copies of what they are going to
publish, which would seem to indicate that they intend to
publish on that date.

I am glad you are not publishing, but to further set expectations,
we do not discuss anything with the submitter (dates for
patches, timelines, our solution, etc...) except if we have
further technical questions to help us understand the problem.

We appreciate you raising the issue, and will be happy to work
with you if needed on this issue, but we will not respond to
publishing threats that put our customer base at risk.

I am currently out of my office until February 11th, and can
only get on line randomly as I'm traveling in the western USA.
So please send all communication to securtiy-alert@...com
so that the team in the office sees the emails and can respond.
