CloudFlare: Sorry, you have been Blocked

kjhambrick · 04-01-2022, 12:03 PM

Dang !

Using AlienBob's chromium-ungoogled

Was trying to upload a script for SCerovec as a .txt file attachment and I see in a popup from

Code:

www.linuxquestions.org/questions/newattachment.php?do=manageattach&p=

Code:

Sorry, you have been blocked
You are unable to access linuxquestions.org

Anyone know how to unblock myself ?

Thanks

You're probably not blocked, only that specific request/file.

It's an attempt at security that triggers on certain strings - see this thread: https://www.linuxquestions.org/questions/lq-suggestions-and-feedback-7/test-4175705379

If you can't modify the file to bypass the block, you'll need to upload it elsewhere and post a link.

Unfortunately this is Cloudflare's doing and apparently jeremy is not able to do something about it.
We can make good guesses as to why CF takes these actions, but nothing more ultimately.

I'm pretty sure (tm) that the browser has nothing to do with it, but who knows, it might be a contributing factor to trigger CF's blocking.

Have a good look at the thread linked by boughtonp.

It's still happening and seems quite arbitrary. The latest incident seems to be that it blocks uname, which I would think is a common, innocuous utility.

(One trick to getting past the filters is to hide an empty [b] [/b] or similar empty markup inside the name to break up the string.)

Ah! That explains why I couldn't help a guy a few weeks ago. I remember that I used that command in my post. Well, at least I now know a workaround.

Code:

rm -rf
uname -a
netcat <somethng>
nmap <something>
curl -F 'file=@afile.txt'' https://www.linuxquestions.org/

<script type="text/javascript" src="https://...</script>

Edit:
Never thought of that, thank you.

And here was that test

rm -rf
uname -a
netcat <somethng>
nmap <something>
curl -F 'file=@afile.txt'' https://www.linuxquestions.org/

<script type="text/javascript" src="https://...</script>

Ok, that gives me more info.

teckk · 08-29-2022, 10:08 AM

What I am trying to write, been working on it halfway for a while, A little tool that will get the format colors made in a syntax highlighting text editor like geany, and format a post suitable for the BB, with those colors, using the BB color/header/bold tags.

I've always thought that would be nifty. So that all bash, python, awk posts I made to this board, could also be syntax highlighted. But doing it manually is not an option, not unless it is 3 lines.

I'm not there yet.

What Turbocapitalist posted, never thought of that before. That adds to it.

That's entirely off-topic. i.e. you need to start a new thread.

(Or stick to using "Preview Post" without actually posting.)
