Summary0013720: Found another db user/password leak
DescriptionAdditional to I found another information leak of the db user and its password. The plain text credentials were stored in /var/log/apache2/error.log, after I accidently misconfigured the name for tine20 database schema. (See additional information as well.)

The logged information should contain a masked password, not the plain text password!

Although the logged file is 3rd Party, the problem is in tine because the 3rd party only throws the exception which seems to be catched into a global tine file. Unfortunatly I was not able to trace a full call stack, so I cannot say which file exactly.

Steps To Reproduce- Open /etc/apache2/sites-enabled/your-tine-site.conf
- Ensure that ErrorLog is configured (default: ${APACHE_LOG_DIR}/error.log)

- open config.ini.php
- change the parameter 'dbname' => 'tine20db' to a not existing name (in my case tine20db by typo)
- save the file (no need to restart/reload the webserver)
- open http://your.tine.server/tine20/setup.php

The request should lead to a white window without any source.

- Open now error.log and see the leaked credentials

The password is not exposed to the frontend, therefore no leak. I'll leave this open in case someone wants to work on it. For it's a won't fix.

Btw. if you think you found a security related issue =>

As the password is shown in error.log, not in tine20.log (a file not expected to be related directly to tine), I'd say, YES, it is a security issue.

A lot of our customers and partners have separate departments for administrating and monitoring the logs. The complete login credentials might be available to the wrong persons. A scenario, that is often not in mind.

i can't reproduce the problem. i only see this in the tine20.log:

* which php version are you using?
* what are the relevant (error-logging) php.ini settings?

Looks like the behavior has changed with the new version 2018.02.2.

The exception is now handled completly in tine20 and not like the first reported exception in zend framework. So I can't reproduce it any more. It's also interesting that you got an "Access denied" instead of an "Unknown database" error like in my example.

You also asked for php version and error settings.
Here they are.
PHP=7.0 (installed by apt)

Error settings in "/etc/php/7.0/apache2/php.ini"
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
display_errors = Off
display_startup_errors = Off
log_errors = On
log_errors_max_len = 1024
ignore_repeated_errors = Off
ignore_repeated_source = Off
report_memleaks = On
track_errors = Off
html_errors = On
