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
CtrlPanel is open-source billing software for hosting providers. In versions 1.1.1 and prior, multiple admin controllers expose DataTable endpoints without authorization checks, allowing any authenticated user to access sensitive administrative data that should be restricted to administrators only. The affected admin controllers define datatable() methods that are reachable via GET requests but lack any permission or role verification. Because the routes fall under the /admin/ prefix, operators may assume they are protected - however, the middleware applied to this route group does not enforce admin-level authorization on these specific endpoints. As a result, any authenticated user (regardless of role) can query these endpoints and receive paginated JSON responses containing sensitive records. Exploitation can result in enumeration of user PII, payment and transaction records, active voucher and coupon codes, role and permission structure, server ownership mappings and support ticket contents. This issue has been fixed in version 1.2.0.

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

Insecure Direct Object Reference (IDOR) vulnerability in CtrlPanel billing software where multiple admin controller DataTable endpoints lack authorization checks, allowing any authenticated user to access admin-only data including PII, payment records, vouchers, roles, server ownership, and support tickets despite being under the /admin/ route prefix.

MitigationUpgrade to version 1.2.0 which contains the authorization fix; for immediate mitigation, add role-based access control middleware to all affected datatable() methods in admin controllers to verify admin privileges before returning data.

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 installed CtrlPanel version
    Locate the version file or check the application header/footer for the version number. Common paths include VERSION file, composer.json, or the admin dashboard 'About' page.
    Affected if Installed version is 1.1.1 or any version prior to 1.2.0
  2. Confirm user authentication is enabled
    Verify that the application requires login for access. Check if unauthenticated requests to any /admin/ route are redirected to a login page.
    Affected if Authentication is required but role verification on admin endpoints is not enforced
  3. Locate DataTable endpoints under /admin/
    Review application routes or use a web proxy to enumerate endpoints matching patterns like /admin/*/datatable, /admin/users/datatable, /admin/payments/datatable, /admin/vouchers/datatable, /admin/tickets/datatable, /admin/roles/datatable.
    Affected if DataTable endpoints exist under the /admin/ prefix and are accessible to authenticated users
  4. Test authorization on admin DataTable endpoints
    Log in as a non-admin or low-privilege user (e.g., regular customer account) and attempt to access admin DataTable endpoints. Use curl or a browser to send authenticated requests to /admin/users/datatable, /admin/payments/datatable, or similar paths.
    Affected if Non-admin accounts can successfully retrieve sensitive data from admin endpoints (HTTP 200 with JSON data returned)
  5. Verify role verification on /admin/ route group
    Examine the application's route middleware or controller code to check if the /admin/ route group or individual DataTable endpoints enforce admin role checks.
    Affected if No role-based authorization middleware is applied to the admin DataTable endpoints

You are affected if CtrlPanel version 1.1.1 or prior is installed and non-admin users can access DataTable endpoints under /admin/ to retrieve sensitive administrative data.

Mitigation

Upgrade to version 1.2.0 which contains the authorization fix; for immediate mitigation, add role-based access control middleware to all affected datatable() methods in admin controllers to verify admin privileges before returning data.

Recommended fix High confidence

1.2.0

  1. Upgrade CtrlPanel from version 1.1.1 (or any prior version) to version 1.2.0 to resolve the improper access control vulnerability in admin DataTable endpoints
