Once again, securityfocus.com refuses to post the truth.

Anyone who has been following the story of the Harvard Business School 
applicants and others who allegedly hacked a Web site operated by 
ApplyYourself Inc. will find the following information valuable.

And you can't get it on securityfocus.com.

Why is that, exactly?

Here's a description of the hack:

http://tinyurl.com/63znp

... the gist of which is ...

ApplicantDecision.asp?AYID=GUID&mode=decision&id=1234567

My point is that once your browser has been assigned the GUID of a
valid/active session, an application status is obtained simply by
entering a seven-digit number and tweaking the URL name/value pairs.

Chances are, the "applicants" who looked at their own application status
were predominantly script kiddies who were having fun poking around by
exploiting the hole.

In case Harvard isn't aware of this, a seven digit number is not
difficult to guess, and if you know your own (or somebody else's) valid
seven digit number, and if the numbers are assigned sequentially, then,
well, there's nothing even to guess...

As Richard M. Smith points out, this could very well be a simple Web
security breach -- but where's the proof that the 119 people actually
did this thing? There is none, and chances are very good that the
security flaw in the Web site allowed anyone to poke around and look at
anyone else's application status just by inserting a seven digit number.

Let's throw out all of the applicants for this year and leave the
Harvard Business School empty to memorialize the dramatic decline in
business intelligence that is caused by computers and the Internet.

Chances are that nobody at Harvard Business School or ApplyYourself Inc.
bothered to contemplate the most obvious scenario: that somebody other
than the 119 accused, or their friends and family, was responsible for
the majority of (or all of) the attempts to access application records.

What information of a personal nature would have been required in order
to access the pending application? Social Security Number? Perhaps it
was possible to browse any one of the pending applications once one had
penetrated the ApplyYourself Inc. security perimeter.

Are 118 applicants being accused of hacking because of the actions of a
single applicant? This is more likely than is the scenario as it has
been depicted.

Unfortunately, even Harvard Business School now believes, in the current
climate of mistrust and fraud in the U.S. Government and U.S.
marketplace, that it is more likely that the 119 applicants just
couldn't wait for their admission answers through proper channels.

Common sense is dead. Long live the Internet.
