Subject locus.apache.org hacked by white hats; FTP down for good, bugzilla down until audited.
Date Thu, 04 May 2000 06:53:02 GMT

Hi.  We have been made aware (thanks to a very humorous banner ad for
Microsoft Back Office on the front of www.apache.org!) that our particular
configuration on www.apache.org of ftpd and bugzilla opened a security
hole that allowed someone from the outside to get a shell account, and
then get root.  We have been in contact with those who found the hole, and
have closed up the misconfigurations that allowed this.

It is important to note that this is *not* a hole in the Apache web server
or related software products.  I would encourage double-checking the
PGP signatures of Apache releases for the immediate future.  

However, I do not believe we are out of the woods yet.  Bugzilla has not
been thoroughly audited, and while I am not worried about ftpd, simply
having another deamon that can write files to the web server whose purpose
has been completely superceded by others suggests that taking it down for
good is the right idea.

So I am taking down FTP - something that should have been done long ago.
If there are FTP links on any of our pages (or on places like freshmeat)
they should be change to HTTP.  There are enough high-quality text-mode
HTTP clients that there is no point to having it up, save for mirroring,
and we allow rsync and cvsup for that.  I will be contacting the mirror
site admins list to communicate this.

Also, I have taken down all installations of bugzilla on apache.org until
it can be audited.  I will be performing a first pass tonight over it, but
anyone else familiar with perl and willing to deal with rather ugly code
is welcome to do so as well.  I will set it back up once I'm comfortable
there's been at least one reasonable pass over the whole codebase and any
obvious holes have been plugged.  This is only life-support though; I
really don't think we should be using bugzilla once a suitable replacement
is found.

Finally, I think it can be said that this compromise was mostly due to a
lack of discipline on the part of those who had root and set up services
without considering the ramifications of the way they were installed.  I
don't want to point fingers, since I'm probably at least as to blame as
others, but I do feel that the policy of giving root access to a larger
number of people than usual was probably a mistake.  Along those lines,
I've changed the root password and removed everyone from group wheel but
myself - sorry to be fascist about this but I kinda feel like at the end
of the day it's my responsibility.  We'll come up with a strategy soon
about granting sudo access to particular people for particular binaries so
that I don't become a bottleneck again.

The details will soon be posted to bugtraq.  Thanks.

	Brian
