Security
May 3, 2006
This article was contributed by Jake Edge.
One would think that an organization would be grateful to someone who found
a vulnerability in their web application and provided them with the
information needed to fix it. A recent
episode where a
security researcher has been charged with breaching
the security of an online database makes it clear that this gratitude
cannot be counted upon, however.
Eric McCarty
found a flaw in the University of Southern California (USC) online application
system that would allow a
SQL injection attack
to extract the contents of a database which included some 275,000 records
of both current students and applicants.
According to the original SecurityFocus
article, the
researcher discovered the flaw when using the system to apply
to USC. The username and password text fields could be used to feed
SQL commands to the database, allowing the entire contents
to be read and/or modified. He then anonymously contacted
SecurityFocus to disclose the flaw.
Other than corresponding with SecurityFocus anonymously, McCarty did little,
if anything, to cover his tracks; believing he was acting in good
faith.
SecurityFocus contacted USC; the administrators of the web site claimed
that only two records could be accessed via the SQL injection. When
confronted with additional records, they admitted that the entire database
was vulnerable and shut down the site for ten days in order to fix it. In
addition, the administrators found the entries in the logfiles corresponding
to the 'attack' and provided the IP address to law enforcement.
The IP address allowed the FBI to determine his identity and to
execute a search warrant against him and his Gmail accounts. On his computer
they evidently found seven records from the USC database and his Gmail account
provided copies of the emails that he sent to SecurityFocus describing
the vulnerability. The charges do not claim that he did anything with
the seven records, just that he possessed them and had gotten them via 'misuse'.
The affidavit filed in the case claims that McCarty caused $140,000 in
damages by causing USC to shut down its system for 10 days. It is
somewhat difficult to see how telling someone about a flaw in their
system makes one responsible for the time it takes them to fix it. It
would seem that the original programmers of the system would be the ones
who are culpable here.
Computer misuse statutes are typically written in such a way that any
access, other than what is intended by the site owner, could be considered
a crime. The intent of the 'perpetrator' rarely seems to be examined
and this case is reminiscent of the
conviction of a
British security consultant last year. Daniel Cuthbert was concerned that
he had been phished at a tsunami relief website and he did two simple tests
to see if the site was for real. These tests set off alarms in an
Intrusion Detection System and ultimately led to his conviction. In addition,
his arrest caused him to lose his job as a security consultant.
It is very difficult to see how these kinds of prosecutions will lead to
a safer internet and, in fact, would seem likely to cause just the
opposite. Even checking for the existence of a flaw is criminal (at least
in some jurisdictions) and actually finding a flaw and disclosing it (not
in a public way, but privately to the affected organization) can lead
to charges in other jurisdictions.
Anyone who thinks they may have
spotted a potential problem area in a web application would be risking a
great deal by probing it further. In addition, administrators of these
sites are unlikely to even look at a flaw unless one can show them an exploit.
Even then, as the first USC response shows, they may be unwilling or unable
to see the implications of the flaw. The sad fact is that the best
response to the discovery of a web site vulnerability may be to keep it to
one's self.
[Editor's note: anybody who informs LWN of a vulnerability in the LWN.net
code will, assuming they have not exploited that vulnerability for their
own gain, be thanked, publicly if desired.]

Brief items
There is a vulnerability in the X.Org
server; it is a buffer overflow which can enable local root access by
way of an X client. If you allow access to your X server from the net as a
whole, this could be a remote root vulnerability - but, presumably, nobody
has done that for years. As of this writing, updates are available from
Gentoo, Mandriva, and SUSE; see the LWN vulnerability entry for
the current list.
Note that this is not the vulnerability so loudly proclaimed recently by
Coverity. That is an older bug which LWN readers knew about last March.
