wn-dusk-plugin: Improper Privilege Management
CVE-2024-32003 is a high-severity improper privilege management vulnerability in wn-dusk-plugin from Wintercms, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. The record lists version 2.1.0 as the first without the flaw, so updating wn-dusk-plugin to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.67% chance of exploitation within 30 days, higher than 53% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update wn-dusk-plugin to 2.1.0 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
Affected products and versions

Official description
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 Dusk's automatic configuration is used (which won't 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 plugin's 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 underlying weakness: Improper Privilege Management
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
How developers prevent this class of flaw
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
