Steps to reproduce

1. Set 'part_file_in_storage' => false, in config
2. Disabled encryption
3. Try to create a file in an SMB share

Expected behaviour

No warning / info / error must appear in log

Actual behaviour

an log line appears

{"reqId":"258b1597-5c50-436b-a2d1-ce0e567db9f5","level":3,"time":"2022-02-05T11:46:26+02:00","remoteAddr":"XXX.XXX.XXX.XXX","user":"something","app":"PHP","method":"PUT","url":"/owncloud/remote.php/dav/files/something/somepath/test.txt","message":"Trying to access array offset on value of type bool at /var/www/owncloud/lib/private/Files/Storage/Wrapper/Encryption.php#434"}

By changing the line 434 from } elseif (empty($encryptionModuleId) && $info['encrypted'] === true) { To

                                   } elseif (empty($encryptionModuleId) && (isset($info['encrypted']) && $info['encrypted'] === true)) {

Server configuration

Operating system: Centos Stream 8

Web server: Apache/2.4.37 (centos)

Database: mysql Ver 15.1 Distrib 10.3.28-MariaDB, for Linux (x86_64) using readline 5.1

PHP version: PHP 7.4.27 (cli) (built: Dec 14 2021 17:17:06) ( NTS )

ownCloud version: 10.9.1.2

Updated from an older ownCloud or fresh install: older

Where did you install ownCloud from: https://download.owncloud.org/community/owncloud-complete-latest.tar.bz2

Signing status (ownCloud 9.0 and above): No errors have been found.

Login as admin user into your ownCloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results into https://gist.github.com/ and puth the link here.

The content of config/config.php:

Log in to the web-UI with an administrator account and click on
'admin' -> 'Generate Config Report' -> 'Download ownCloud config report'
This report includes the config.php settings, the list of activated apps
and other details in a well sanitized form.

or 

If you have access to your command line run e.g.:
sudo -u www-data php occ config:list system
from within your ownCloud installation folder

*ATTENTION:* Do not post your config.php file in public as is. Please use one of the above
methods whenever possible. Both, the generated reports from the web-ui and from occ config:list
consistently remove sensitive data. You still may want to review the report before sending.
If done manually then it is critical for your own privacy to dilligently
remove *all* host names, passwords, usernames, salts and other credentials before posting.
You should assume that attackers find such information and will use them against your systems.

List of activated apps:

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.

Are you using external storage, if yes which one: local/smb/sftp/...

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP configuration (delete this part if not used)

With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';


Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.
