Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Devolutions Server version
    Locate the installed version of Devolutions Server through the administration console under System Information, or by checking the product about page within the application. Compare the version number to the affected range: versions prior to 2024.3.6.0 are vulnerable.
    Affected if The installed version is 2024.3.4.0 or earlier, or any version below 2024.3.6.0
  2. Verify web extension restriction feature is configured
    Access the administration panel and navigate to the web extension restriction or browser extension policy settings. Check if any extension blocking rules have been defined by administrators.
    Affected if Extension restriction policies are configured and enforced in the environment
  3. Confirm user role configuration
    Review the user role assignments in Devolutions Server to identify which authenticated users have access to the system. Check if any roles have permissions related to extension management or policy modification.
    Affected if Multiple authenticated user roles exist in the system, particularly non-administrative roles
  4. Test extension restriction enforcement
    As a non-administrative authenticated user, attempt to use or access a browser extension that should be blocked according to the configured policy. Verify whether the restriction is properly enforced or can be bypassed.
    Affected if Authenticated users can access extensions that administrators have configured to be blocked

A user is affected if their Devolutions Server installation is version 2024.3.5.0 or earlier and the web extension restriction feature is configured with blocking rules that could be bypassed by authenticated users.
