I would, do you agree that silverstripe has a security issue? No?
Alright
you owe me a beer.
Linking to your personal site doesn't make me think you are any more
security conscious. The fact that you doubt this security issue so much
because it can be fixed with a *third party* tool, makes me think that
you don't have a full understanding. What if you were on a shared
hosting
provider that used fail2ban, and said it was secure, then suddenly they
took it away because they thought underlying issues were resolved, then
suddenly that opens up holes in the underlying application...
Also, L7 attacks are anything on the application layer. Yes, F5 can stop
most of these attacks, some require fine tuned rules, but ... can you
pay
for an F5 for everyone on this list? I don't think that people should be
required to use an expensive solution such as F5 for something that
could
just be a blog...

If so - http://tvfedor.ru - try to find anything here. If beer isn't
enough - tell your price (but keep in mind that in case if you fail -
you're the person to pay). Fair deal?
PS: when I said L7 attacks I meant brute F5-based ones, not the

The thing is - even if there was no such "vulnerability" - you
still
would be able to "DOS" silverstripe-based site with a bunch of
requests just because the cost of generating a request is
dramatically
higher than the cost of a generating responses.
So the "issue" is overrated. For someone who can google and is not
a
total dumb - any level7 attack issues can be solved easily.

There are a few questions to raise here:
1. Why can a member of the public flush the cache?
2. Why has the NZ government chosen Silver Stripe over something
like Drupal, or other alternatives?
3. Does the government service providers have the knowhow and
capabilities to detect and prevent such attacks?
4. If someone did manage to use this, or something similar, what
websites would it effect and how would the public be affected?

It's actually pretty obvious that non-cached page takes longer to
generate (while I agree it's weird they provide a switch to flush
the cache) :-) Anyway, it's well known that the most resources
consuming part of almost every project is captcha generating

It's a pretty script-kiddy attack that can be defended in minutes
