“And the best code in this case is code you didn't write as PHP's session handler is battle-tested”

cPanel is written in perl.

cPanel is 30 years old, are you saying it's not battle tested, boring, proven, and widely audited?

In fact PHP is only a few months older than it.

I don't even know why you'd want to re-implement this stuff, too. It's not exciting or sexy work. It's like time parsing, time zone handling, leap years... Why would you want to inflict that on yourself? You will 100% not handle every edge case, and you will 100% get time and time zone handling bugs.

But it's not the same thing every time, for example if you had written 'your own' http request you wouldn't habe been hit by the axios vuln.

If you rolled your own crypto and didn't install AF_ALG, you would have avoided copy fail.

Even in this case if you had implemented your own control panel, you wouldn't be hit.

Actually roll your own, don't add dependencies

I doubt the mantra of "don't roll your own Auth/crypto" - especially if it lives on a server where the code can't be inspected.

Sure, there will be more bugs in my code, but the attackers will be putting far more scrutiny into a widely used library.

Some deliberately hilariously weak auth I built decades ago is only just now starting to get broken into by AI bots, whereas any vulnerable wordpress was broken into within days.

At the rate we are going, we will all go back to publish HTML website like in Geocities times.

> Good on these companies to publish their findings straight away as I'd imagine that both bugs would have fetched quite a lot on the black market.

You should read the other thread regarding copy fail and the gentoo maintainer. I haven't seen so many unhinged and outright rude comments on a security topic since the good old days of slashdot and x vs. y controversy of the day.

I wonder what the reason behind so much hostility is. Is it gentoo or the kernel folks or the fact that the company that found it used "AI"? No idea, but it was a weird read.

I used to help nonprofits and small businesses build websites. Process always went like 1. buy domain, 2. buy a shared hosting provider that one-click-installs Wordpress, 3. use a theme to begin editing the website. Often, I would also use the email included with that hosting provider for the firm.

ALL of that goes through cpanel, for every shared hosting provider I can ever remember using. Even if the stuff happening on those servers didn't use perl, cpanel itself -- the admin of everything provided for that domain by the hosting provider -- it's a huge surface area.

I still deploy a bunch of simple sites, built around the CGI::Application framework.

I understand how they work, I'm familiar with HTML::Template, and related modules, so I can hack up a quick interactive/dynamic site in a couple of hours.

They're no longer things I'd run on the public internet, but for quick internal things it's very easy to deploy a container with a perl backend.

Why? This one gives you a root shell directly, no need for an LPE.

definitely don't expose any management interfaces to the open internet.

personally, i manage my homelab through ssh via the commandline, and key-based ssh auth is secure enough for my threat model (i am considering switching the entrypoint machine to a BSD though, to avoid the kind of bugs distros sometimes introduce).

but a webserver and a few containerized services seem pretty low risk to me, so i do have a few of them exposed via reverse proxy. The more sensitive one behind Authelia via the forward-auth pattern, which i feel like is a really good fit for homelabs.

cPanel is just about as far away from “unproven” as possible.

Really not looking forward to a regulated software industry. It will cause a lot of gatekeeping and bureaucracy. It's one of those things that may seem good, but in practice, it's pure waste in every way imaginable. Will just lead to exclusivity, gatekeeping and artificial friction. This is a hill I'm willing to die on. Those making software have plenty of incentives to make it good, and bad software is punished already to the fullest extend (because it's not fun to get compromised or your reputation ruined; this is a natural incentive)
