While entering a reply in another thread on the Framework Forum, a message box popped up with the helpful text: 403 forbidden. Simultaneously I noticed that the message ‘preview offline’ had appeared below the preview of my posting to the right of the edit box.
I faffed around and narrowed the cause down to a specific sequence of characters. I’ll type them here with extra space characters.
$ cat / proc / cmdline
Type the string as slash-proc-slash-cmdline and the edit tool will break.
The spaces ensure that the bug is not triggered. However they also completely alter the meaning of the above Linux command.
Since this forum is aimed at both Linux and Windows users, it would be great if this bug could be better characterized and ultimately fixed.
I think you’re onto something. I decided to search the forum using its native tool to see if anyone had ever managed to post the string that causes the problem. Among Linux users this would not be a frequently-typed command however on this forum I’d expect it to appear a few times.
The ‘403 forbidden’ message box pops as soon as you type the slash-proc-slash-cmdline sequence into the search edit control.
Odd, it’s either doing the blocking intentionally…or it’s trying to access / execute something and getting blocked. Funny thing is that 403 is from the HTTP side of things…as if there’s an application firewall filtering the content and giving an HTTP response code.
Respect this! Yeah, this is also outstanding. Most stuff will post fine. It’s oddball code that does this.
It’s…complicated and I am working with the web team on this. It’s not as simple as filtering it turns out, it’s at a different level I can’t get into. And yes, it’s frustrating. We have to be careful on what solutions as to avoid creating another issue that would be far more concerning.
