Extremely wrong. I'm not sure how "RCE on every PHP server, from anywhere on the internet, no other requirements" could possibly be underblown by anyone. Exploiting the PHP request parser bypasses basically all security checks and it doesn't matter how secure your code is because the exploitable component runs before your code and can't be disabled.
I am very curious to hear why you thought it was overblown.
There was also that other guy who posted "steal my bitcoin" on a vulnerable PHP server with the private keys to prove it was overblown, and got his bitcoin stolen within a day.
"There was also that other guy who posted "steal my bitcoin" on a vulnerable PHP server with the private keys to prove it was overblown, and got his bitcoin stolen within a day."
Part of the confusion is that the initial PR for the release made it sound like there was a ready-to-go exploit that was just push button, get shell on any PHP server in the world. That turned out not to be the case, as evidenced by the fact that the number was 19 hours and not 19 minutes.
But the fact that it was 19 hours and not "never" also does provide a data point that everything that was vulnerable really was vulnerable, it just may not have been quite as vulnerable as it was initially presented. Still plenty vulnerable, of course.
My point here being that the initial 24 hours were very confusing and I think it's worth remembering that and giving people grace for it. Even now, I've heard rumors of an exploit that does work on all boxes without making changes for a specific target but I'm not actually sure whether that exists or not. (Any further info welcome.)
Shutting down half the internet was the right move. If it took someone 19 hours to exploit a site, you'd better have shut it down before 19 hours and not after.
I don't see what was confusing about the initial 24 hours. GP was correct, the description of the bug made it clear it was a very high risk.
Also, unless I am reading this wrong, it does not seem like what actually got the bitcoin was a 2shell-like exploit? Seems like memory corruption leading to printing out the flag through just http requests? How would you use this outside of a CTF context?

It could be overblown if it's not true. The amount of time it took for anyone to claim the Bitcoin from the supposedly-vulnerable PHP site convinced a lot of people that the vulnerability was not as bad as claimed.
wasn't it setup in an unexploitable configuration (not actually serving a php page IIRC?) for most of the time, and then got popped within like 2 hours once fixed?
I think it goes back to the huge amount of anti-AI sentiment that's out there today. Any AI accomplishment gets undersold by haters, i.e. people maintaining that the Navier-Stokes solution was stolen, people saying that Lean proofs can't be relied on, exploits like PHP2Shell are esoteric and not usable in the real-world, etc. Those are just comments I recall reading off the top of my head but I could find sources if anyone wants. I think it's just a way for people to cope and fool themselves into thinking that this whole AI thing isn't a big deal and will just blow over.

Not having made the claim (took down my website too), but because PHP is not connected directly to the network. While you cannot prevent PHP from being overtaken from inside the PHP program, you can prevent PHP being executed on malicious data by configuring the webserver. It's overblown in the sense that it would be even more serious if the same happened in the webserver itself.
Its overblown in the sense that 70% of the internet was not in fact vulnerable, as widely reported. And not everyone is a hackor because they have access to llms. Go look at normie coverage from people like Linus tech tips and you'll see them saying how millions of servers were under attack by script kiddies with llms, amd how llms are so dangerous.
The whole thing was basically a psyop, whether intential or not idk but Califs research was funded in part by OpenAI so there's that.
I agree. There's nuance to it. I believe the CVE was overblown, and I also believe that it is a severe vulnerability that should be addressed ASAP. 2 things can be true at once.
It was OpenAI's marketing that hyped up the vulnerability to the point that guys on my hockey team saw it in the news and were asking about it. There doesn't need to be mainstream articles about it, these kinds of vulnerabilities happen every year. Just patch and move on.
Respect, hats off to reevaluate when presented with the info. Will fully admit, I myself lacked the ability to assess the true severity, mainly cause I try to stay away from PHP since my first encounter in sixth grade, so was going a bit back-and-forth due to what I was reading.
Mainly saw the severity in the economic impact of having to quickly patch so much, but taking offline being the right choice given the risk, along with of course all the decades old, never patches, blogs being botnet targets someday in the future, akin to Wordpress being commonly used for Ransomware hosting for similar reasons. And of course hopefully learning something from the timeline and leak for future disclosures. Feel things need to generally change from the status quo, barely has changed since the 2015 Google/MSFT squabble...
Yes, you were. These exploits are happening in processes like php-fpm before it actually executes any code for the web application, so its not like you need to find endpoint where a specific class is being invoked or anything like that.

It's not 19hours. The server was originally configured with no running php. Once they added a php file, the server got pwned in 2 hours.

Can you? Initial suggestions to block multipart content-types were a red herring.

I commend you to having corrected your thoughts this publicly fwiw.
We need more of this.
