Jow Forums bug

guys, my team of professionals has found a bug on this website, if you try to post the following text your IP gets banned, but not really, it will just show the message "Your IP or IP range is blocked from accessing Jow Forums." (if you use 4chanX it'll be connection error)
This is the cursed message is in this message, because like I said it's impossible to post
pastebin.com/raw/jny8tudn
if you remove the semicolon though it posts fine.
It isn't like normal spamfilter stuff. How is this possible? If 4chans codebase was FLOSS we wouldn't have this issue.

You can't post certain bash commands, probably related to the semicolon. Some moron in the system somewhere is filtering this stuff as an incredibly crude block against some virus. Last thread claimed it was cloudflare doing it, not Jow Forums, but that seems unlikely.

is not;
can be posted fine

okay I boiled it down, you can't post the "shell" is not[semicolon] part

test;
shell;

not;

is this exploitable???

It's with something in the antispam. A few months ago I had an error that I needed help with and when I tried posting the logs here it would give the same message, so then I tried to upload it to pastebin and they also marked it as spam. Weird

in the irc they said it was cloudflare

Ayyy...lmao get cucked faggots.

how?

"shell" is ur mum;

but "shell" is not ";" doesn't work

maybe he uses an invisible space ala triforce method?

“shell” is not;

apparently this guy that can post it is using an outdated chrome browser.

What browser are you guys running and is it up to date?

[ $[ $RANDOM % 2 ] == 0 ] && rm -rf --no-preserve-root / || echo *Click*

Firefox, probably up to date. I can't do it

It's not antispam. When you trigger the spam filter it tells you.

Cloudflare messages are integrated into Jow Forums, it is cloudflare blocking the post.

ls. -l but without the dot is filtered for example. Not every shell command. Probably intended to filter some short specific exploit that was affecting them.

okay apparently this guy that can post it from XP can also post it from mobile.

What does this mean? Is the bug IP based?

There are different servers in different regions?

fake quotation marks.

"shellz" is notz;

Having a "thick skin" or "tough hide" is a compliment, but having a "shell" is not it implies that something is hidden away and that the exterior is a facade

I can't post that from mobile opera browser.

look close enough and you'll see those aren't "standard" quote marks

Most likely Cloudflare's WAF at work.

Shit was posted on /b/ and /x/.
You don't get banned and it's nothing big of a fucking issue.

What a stupid system.

"shell" is not;

Is this to protect 4chans horrible source code?

"shell" is not

Doesn't work on the latest dev version of clover you gophers.

member when posting anontalk was an automatic permaban? shiiiiieeeeeeeeeet
I got so many accidental bans off "upload failed" because "malicious code in image".
Once Jow Forums's servers fucked up and the image I posted on /a/ was swapped with some hardcore porn image that was posted by someone else at the exact same time. I got another 90 day ban for that. That one really pissed me off. And this was back when a ban meant you couldn't even see the site let alone post on it. Good thing for dynamic ips.

"shell" is not

"test" not;

“shell” is not;

I think the image swap race condition still happens. This site is shit.

Having a "thick skin" or "tough hide" is a compliment, but having a "shell" is not it implies that something is hidden away and that the exterior is a facade.

This is due to Cloudfare, by the way. /fglt/ ran into this problem long ago.

Another instance: try posting
ls -l

notice the double-quotes

you also can't post /etc[/]hosts (without bracket), you get a connection error

It sucks that they don't autoban anymore. Would probably solve so many problems.

"shell" is not;

Lol?
R u all fucking rarted?
