Tons of sites are currently offline to hopefully prevent an attack until they can update PHP; just the things I've run into this morning: OBS, TicketTailor, tons of wikis...
Which kind of makes sense, I think a lot of Dutch websites have been taken offline. I think it’s due to recent regulations that have been introduced.
I think, given the (supposed) seriousness of this issue, it’s an adequate response. I suspect Cloudflare et al will have rules added to their managed WAFs within a few hours after release as well.
That said: it seems like the core issue is that they can’t release PHP publicly without revealing the exploit, wouldn’t it have made more sense to coordinate in the background with these organizations, and important distros, so that this could have been patched without revealing the exploit?
But they say it's a stopgap and still advise patching. It makes sense, since their tweet also says "are updating mitigations as new vectors show up" so it seems like there are many ways to exploit this, whatever it is.
I don't know. Still, at a time like this I would expect a 99% static public website to be up, running and serving all comers. This is a complete mission fail, both in terms of using PHP and in terms of not having a fall-back plan in place.
Not all hacks are used to steal data. It's an authoritative website. If this hack is used to host a fake PHP fix stuffed with credential stealers then you have a problem.
Oh I absolutely agree they should take it offline until the fix is ready, I just mean that the NCSC itself is very much still operational even if their public website is temporarily offline. Like a computer with the monitor switched off.
PHP is going to publish the patch in 5 minutes, right? On their website which runs on... Perl Catalyst? Ruby on Rails? Django? What could possibly go wrong?
