Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Web interface of Evolution Controller Versions 2.04.560.31.03.2024 and below contains poorly configured access control, allowing for an unauthenticated attacker to update and add user profiles within the application, and gain full access of the site.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Evolution Controller web interface versions 2.04.560.31.03.2024 and below contains a broken access control vulnerability that allows unauthenticated attackers to directly access user profile management functions. Due to missing or inadequate authorization checks on sensitive endpoints, an attacker can create new user accounts or modify existing ones, potentially escalating privileges to administrator-level access and gaining full site control.

MitigationImplement proper authentication and role-based authorization checks on all user profile management endpoints, ensuring that unauthenticated requests are rejected and only authorized users can modify profiles. Apply the vendor patch as soon as available.

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. Identify Evolution Controller version
    Check the software version displayed in the Evolution Controller web interface login page header, or query the server for version information via the application's built-in 'About' or 'System Info' page typically found at /about or /system/status endpoints.
    Affected if Version number is 2.04.560 or lower (e.g., 2.04.560.31.03.2024, 2.04.500, etc.)
  2. Locate user profile management endpoints
    Review the application's URL structure for endpoints related to user management such as /user, /users, /profile, /user/add, /user/edit, /admin/user, /api/users, or similar paths that handle account creation or modification.
    Affected if These endpoints exist in the web application
  3. Test unauthenticated access to user creation
    Send an HTTP GET or POST request to the identified user creation endpoint (e.g., /user/add or /api/users/create) without providing any authentication credentials or session cookie.
    Affected if The request is accepted and returns a user creation form or success response rather than redirecting to a login page or returning 401/403
  4. Test unauthenticated access to user modification
    Send an HTTP request to an existing user modification endpoint (e.g., /user/edit?id=1 or /admin/user/update) without any authentication tokens.
    Affected if The endpoint displays user details or allows modification without requiring login credentials
  5. Verify authorization enforcement on sensitive endpoints
    Intercept an authenticated session, then attempt to access user management functions using the same session token on a different browser or incognito window without re-authenticating.
    Affected if The application permits access to administrative user functions without re-validating credentials or returns user data without proper authorization checks

A defender is affected if the Evolution Controller version is 2.04.560 or lower AND user profile management endpoints are accessible without any authentication credentials.
