Hello Jon,
Great points.
I think an even worse attack would be what happened to WordPress not too long
ago, the code itself on the distribution servers was tinkered with.
Wow, that's really awful. Didn't know about that.
It's a little unfair to point out XSS as being only a Joomla issue.
I didn't mean to say Joomla only has XSS problems...in fact, I don't think I
did.
I've used snort in the past, and tripwire. I find snort tough, because you have
to keep
up w/the signatures, and thus requires time and attention. In a small company
such
as mine, I'd love to set it up, but I don't have the time to monitor and adjust
it.
Plus, snort is not the end all be all. Its signature based detection, and as
far as I know
doesn't address polymorphic code. But snort is a key part to an overall strong
detection
system.
Great link BTW, I haven't messed w/snort in years.

I think an even worse attack would be what happened to WordPress not too long
ago, the code itself on the distribution servers was tinkered with. It's a
little unfair to point out XSS as being only a Joomla issue. It happens to any
software that lingers past even a single minor 0.1 upgrade, including C
libraries and such.
The bottom line is if you are shared hosting you are leaving "security" in
the hands of your ISP period. If you are running your own boxes and don't have
things like Tripwire or Snort running you are going to be unaware of such
attacks anyway.
One of better ways to keep up on it is to monitor files like Bleeding Edge
for software you are running ...

Hello again,
I've always had an interest in security. Not too long ago a friend was
looking
into deploying joomla for a client. He's a pentester/researcher for a very
well
educated and influential firm = ] , so he had to make sure it was going to
be secure.
He started researching and found that many joomla installs had/have been
comprimised
via XSS attacks.
Today, he posted the link of a site that had been owned by XSS and the
crackers installed this
web based backdoor script.
I grabbed the script and included it here
http://www.projectskyline.com/phplist/r57shell.txt
to show PHP developers AGAIN how important security is and give us an
inside look at
some of the tools our enemies are armed with.
For those that deploy joomla, this is especially something to watch for.
For everyone else, just something to checkout.
You'll notice this script enables:
- Mail to be sent out (w/or w/out files attached)
- Commands to be run.
- Search for SUID, writable directories, files, tmp files., .(files) ...
- Outgoing connections to be established
- Some kind of IRC implementation
- SQL to be run
- Files can be downloaded and uploaded
- and much, much more.
