You simply have to deny access for the folder /apps/rainloop/app/data inside your Nextcloud installation.
I only use nginx, but here you have to define a location block inside your Nextcloud vHost:

        location ^~ /apps/rainloop/app/data {
                deny all;
        }

You’ll need something similar for Apache.

Added in /etc/apache2/sites-enabled/nextcloud.conf

<Directory /var/www/nextcloud/apps/rainloop/app/data/>
Require all denied

<Directory /media/USBdrive/data/rainloop-storage/>
Require all denied

Sudo service apache2 restart

  1. Also tried
    …
    AllowOverride All
    …

and added .htaccess with
Require all denied
in the subsequent directories

Sudo service apache2 restart

No results.
Still get the warning… Any clues ?

Would be interested in a solution as well.
I have setup Rainloop yesterday and struggeling getting rid of the error.
My “data storage” is located outside the WWW directory on a mounted NFS share, this is also the location of rainloop_storage. rights are assigned to www-data but still. I have no idea how to get rid of the error.

What I tried

apache2.conf
<Directory /media/nfs-share/rainloop_storage/data>
   Options -Indexes
   Deny from all
</Directory>
<Directory /var/www/html/nextcloud/apps/rainloop/app/data>
   Options -Indexes
   Deny from all
</Directory>

and .htaccess in media/nfs-share/rainloop_storage/data and /var/www/html/nextcloud/apps/rainloop/app/data

Deny from all

With www-data:www-data as owner

Still the same error, I I try to access the data directory somehow from the browser, I get redirected to Nextcloud file view

I cannot access the Rainloop storage folder from any browser. Ubuntu 16.04, Apache 2.4. There is the .htaccess file from the /data/rainloop-storage folder actually:

/data/rainloop-storage# cat .htaccess 
Deny from all
<IfModule mod_autoindex.c>
Options -Indexes

It should put these files into the data directory too to prevent access from outside:

/data/rainloop-storage# ls
_data_  index.html  index.php  INSTALLED  SALT.php  VERSION

If this is not the case then something with your installation went wrong. The files are generated here:

#6

None of these files were created.
Not sure if I can do anything wrong when activating an app from nextcloud directly, but ok.

Is there a log of things going wrong?
Do I need to place the .htaccess now into
/media/nextcloud-data/rainloop-storage/_data_
or
/media/nextcloud-data/rainloop-storage/
or/and
/var/www/html/nextcloud/apps
or
/var/www/html/nextcloud/apps/rainloop/app

This is all not really documented, nor do I understand completely how and what is parsed when.
Perhaps it is even a bug, because all files are there accept this ones, seems strange.

#7

It should in the data folder like /var/www/nextcloud/data/rainloop-storage/.

Could be, maybe you should report a bug if the files are not created. Did you check the permissions on that folder?

#8

Thanks, I filed a bug because I am out of ideas

Hello, this issue is mentioned in this ticket: https://github.com/pierre-alain-b/rainloop-nextcloud/issues/62.

Our analysis so far is that:

  • the data folder is not accessible
  • it is a false positive triggered by the fact that Rainloop checks the status code of the request to one file in the data folder but as Nextcloud redirects the request with a 3xx status code then Rainloop does interprete this as an insecured folder

I should push a change in the Rainloop base code to differentiate a “true” access and a redirect by Nextcloud.

Unless I miss something, there is no security risk for now even with the error message popping up.
