wn-dusk-plugin (Dusk plugin) is a plugin which integrates Laravel Dusk browser testing into Winter CMS. The Dusk plugin provides some special routes as part of its testing framework to allow a browser environment (such as headless Chrome) to act as a user in the Backend or User plugin without having to go through authentication. This route is [[URL]]/_dusk/login/[[USER ID]]/[[MANAGER]] - where [[URL]] is the base URL of the site, [[USER ID]] is the ID of the user account and [[MANAGER]] is the authentication manager (either backend for Backend, or user for the User plugin). If a configuration of a site using the Dusk plugin is set up in such a way that the Dusk plugin is available publicly and the test cases in Dusk are run with live data, this route may potentially be used to gain access to any user account in either the Backend or User plugin without authentication. As indicated in the README, this plugin should only be used in development and should NOT be used in a production instance. It is specifically recommended that the plugin be installed as a development dependency only in Composer. In order to remediate this issue, the special routes used above will now no longer be registered unless the APP_ENV environment variable is specifically set to dusk. Since Winter by default does not use this environment variable and it is not populated by default, it will only exist if Dusks automatic configuration is used (which wont exhibit this vulnerability) or if a developer manually specifies it in their configuration. The automatic configuration performed by the Dusk plugin has also been hardened by default to use sane defaults and not allow external environment variables to leak into this configuration. This will only affect users in which the Winter CMS installation meets ALL the following criteria: 1. The Dusk plugin is installed in the Winter CMS instance. 2. The application is in production mode (ie. the debug config value is set to true in config/app.php). 3. The Dusk plugins automatic configuration has been overridden, either by providing a custom .env.dusk file or by providing custom configuration in the config/dusk folder, or by providing configuration environment variables externally. 4. The environment has been configured to use production data in the database for testing, and not the temporary SQLite database that Dusk uses by default. 5. The application is connectable via the web. This issue has been fixed in version 2.1.0. Users are advised to upgrade.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
