Executive brief
CtrlPanel, an open-source billing and management platform for hosting providers, contains a security flaw where administrative data tables are accessible to any logged-in user. This allows standard users to view sensitive information that should be restricted to administrators, including customer personal details, payment transaction IDs, and support ticket contents. Such exposure could lead to privacy violations, financial abuse through stolen discount codes, and targeted phishing attacks against customers.
Technical details
Multiple admin controllers in CtrlPanel (including UserController, PaymentController, and TicketsController) expose `datatable()` methods via GET requests without performing role or permission verification. Although these endpoints reside under the `/admin/` route prefix, the applied middleware fails to enforce administrator-level authorization. An authenticated attacker with low privileges can query these endpoints to receive paginated JSON responses containing PII (emails, IP addresses), payment processor transaction IDs (Stripe/PayPal), active voucher/coupon codes, and support ticket message bodies. The vulnerability is addressed in version 1.2.0 by implementing explicit authorization checks within each affected controller method.
