Can't save custom TV with certain string

Hi

If I enter

/about

into the content field of my custom template variable (input type Rich Text or Textarea) and try to save, I get a blank page with the following error message:

{"success":false,"message":"Access denied.","total":0,"data":[],"object":[]}

I was able to save any other string so far.

I tested on two different shared hosting environments and this bug only shows up on one of them. So I assume the bug is related to the server environment. On both hostings I use Revo 2.1.3-pl on LAMP, satisfying the MODX Revo requirements http://modx.com/revolution/developer/requirements/. And I can’t see any relevant differences in the PHP configuration.

Any help is much appreciated,
Werre

I still couldn't solve that one.
- In which technical context "/about" is a forbidden/sensitive string?
- What other strings could be affected?
Thanks!

Can't help with the issue itself - don't see any reason why that should be 'forbidden'. Could be something up with TinyMCE in combination with your server.

However, what happens if you remove the '/' from the beginning of the string? Could you perhaps add that in the template instead, or as an output filter?

Thanks, Lucas, for motivating me to do some more testing.

- '/about': does not work
- '/ about': works
- '/test' or any other tested string after a slash: works

The error only occurs when entering the string via TinyMCE (plain text works).
And it only occurs when using custom TVs (Resource Content works).
I tried all 3 different entity encodings from the TinyMCE sytem settings.

After all, its easy to bypass this problem, so I can live with it.
But I can't insert an image out of a directory named 'about', for example.

Do you have a physical folder on the server named about/ ? Or any .htaccess rules that might be intercepting the requests?

Yes, I had the folder structure /assets/images/about/. I discovered the problem because I couldn't insert images out of that directory (via TinyMCE into custom TV). No problems with other directories, though.

I have the basic .htaccess file from the MODX build, extended with suPHP_ConfigPath, the path to the php.ini file. Nothing critical IMO.

Some testing on another installation on the same shared hosting shows:
- Infinite saving loop instead of the error message.
- '/abou' works
- '/aboutx' does not work [ed. note: webaff.ch last edited this post 12 years, 8 months ago.]
