| 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." 19 hours: https://stealmybitcoin.com/ 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.) |

| ▲ | NitpickLawyer 3 hours ago | parent | next [-] | | 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. | | |

| ▲ | kylestanfield an hour ago | parent [-] | | In online communities right now there’s a lot of demand for evidence of LLM capabilities being overblown. It’s unfortunate that even if the steal my bitcoin creator apologizes for spreading misinformation due to incompetence, the truth won’t be spread as widely. |

| ▲ | cowlevel 3 hours ago | parent | prev | next [-] | | 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. | |
| ▲ | beepbooptheory 3 hours ago | parent | prev [-] | | 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? https://github.com/KillaBoi/StealMyBitcoin-PoC | | |
| ▲ | cowlevel 3 hours ago | parent [-] | | 2shell is catchy shorthand for "do anything". log4shell (originator of the name?) didn't directly give you a shell either, it ran some Java code. You could have a shell if you wanted to. |

| > I'm not sure how "RCE on every PHP server, from anywhere on the internet, no other requirements" could possibly be underblown by anyone 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. |

| ▲ | tkz1312 4 hours ago | parent [-] | | 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? | | |
| ▲ | lifeisloving 4 hours ago | parent [-] | | The point is, under normal configurations when you're serving the PHP server correctly with table-stakes best practices the server is not exploitable This was not a scary vuln at all. | | |
| ▲ | literalAardvark an hour ago | parent | next [-] | | Under normal configurations the server is highly exploitable. It's a horrible vuln and I don't understand what's with all the flat infosec society coming out of the woodwork. The challenge server had vibe coded infra that made it hard or impossible to hack, but it was a configuration that can't be used in production and no one uses ( it was deployed as a PHP static content server instead of a dynamic site generator ) | |
| ▲ | Urd- 3 hours ago | parent | prev | next [-] | | Normal configuration of a PHP server is to not run any PHP code and serve a static html file? | | |
| ▲ | lifeisloving 2 hours ago | parent [-] | | Where is all the evidence of exploits if most of the webs PHP servers were vulnerable? This is a seperate chained exploit itself, seemingly executed by a nation stae. There are thousands of exploits infiltrating web servers around the world daily, and they arent php2shell. You only care about this because it falls into a weird viral narrative about "AI saftey". | | |
| ▲ | literalAardvark an hour ago | parent [-] | | There's nothing separate about this. Chained just means they used php2shell to run a local privilege escalation. | | |
| ▲ | lifeisloving 7 minutes ago | parent [-] | | Was the exploit not dependent on a kernel exploit that was disclosed and patched in may, or am I just hallucinating? |

| > I am very curious to hear why you thought it was overblown. 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. |
| |
| ▲ | cowlevel 3 hours ago | parent [-] | | Can you? Initial suggestions to block multipart content-types were a red herring. | | |
| ▲ | 1718627440 2 hours ago | parent [-] | | In theory yes. In practice, I don't know, I hope my provider patched it properly. | | |
| ▲ | cowlevel 2 hours ago | parent [-] | | What specific configuration would you recommend to block the vulnerability without actually patching it? | | |
| ▲ | 1718627440 2 hours ago | parent [-] | | None. Like I wrote "I don't know, I hope my provider patched it properly." | | |
| ▲ | cowlevel 2 hours ago | parent [-] | | Then why did you say > you can prevent PHP being executed on malicious data by configuring the webserver. | | |
| ▲ | 1718627440 an hour ago | parent | next [-] | | You can do this. I don't know how, and I don't think it's a feasible use of my time, to find out how. It's obviously computable on a Turing machine, because they were able to patch PHP. | | |
| ▲ | cowlevel 28 minutes ago | parent [-] | | So it was useless advice? You presented it as if anyone not following the advice is incompetent, now you suggest nobody knows how to do it. Is everyone incompetent? | | |
| ▲ | 1718627440 4 minutes ago | parent [-] | | What? I never claimed it was "advice"? I explained how other people could have arrived at the conclusion that there can be worse things than a single language interpreter being vulnerable to a unconditional RCE. Were you answering to the wrong comment? |

| 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. |

| 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. |

| ▲ | robby_w_g 3 hours ago | parent [-] | | 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. | | |
| ▲ | literalAardvark an hour ago | parent | next [-] | | The CVE was not overblown. It's correctly marked as a 9.2. Random bloggers jumped on it and said dumb blogger things. That is all. This is one of the worst vulns ever and the security response from the people who actually secure things for a living was entirely warranted regardless of whether some blogger thought it was the AI apocalypse or not. | |
| ▲ | cowlevel 3 hours ago | parent | prev [-] | | This was a vulnerability worse than Heartbleed. Did they hear about Heartbleed? |
