CtrlPanel is an open-source billing and management platform for hosting providers. A security flaw in the administrative role management interface allows an authorized administrator to inject malicious scripts into the system.

Technical details

A stored cross-site scripting (XSS) vulnerability exists in CtrlPanel versions 1.1.1 and prior within the `datatable()` method of `app/Http/Controllers/Admin/RoleController.php`. The application interpolates `$role->name` and `$role->color` directly into a `<span>` element's HTML and style attributes without sanitization. Furthermore, the use of `.rawColumns(['actions', 'name'])` instructs the DataTables component to render the output as raw HTML, bypassing automatic escaping. An attacker with administrative privileges to create or edit roles can inject a malicious payload (e.g., `<img src=x onerror="...">`) that persists in the database and executes in the browser of any administrator who visits the `/admin/roles` page. This issue is resolved in version 1.2.0.
