CVE-2026-34246
CtrlPanel: Stored XSS in Admin Role Management via Unescaped DataTable HTML Output
Description
CtrlPanel is open-source billing software for hosting providers. Versions 1.1.1 and prior contain a Stored Cross-Site Scripting (XSS) vulnerability exists in the admin role management interface. In app/Http/Controllers/Admin/RoleController.php, the datatable() method interpolates $role->name and $role->color directly into a <span> element's HTML and style attribute without sanitization, and the chained .rawColumns(['actions', 'name']) call instructs DataTables to render the name column as raw HTML, bypassing automatic output escaping. An admin with role creation or edit permissions can inject a payload such as <img src=x onerror="alert('XSS_POC')"> into the name or color fields, which is persisted to the database and executes in the browser of every admin who loads the /admin/roles page. This enables session hijacking via cookie theft, credential harvesting through fake login prompts or keyloggers, lateral privilege escalation by performing admin actions on behalf of victims, and a persistent backdoor that re-executes on every page load until the malicious role record is removed. This issue has been resolved in version 1.2.0.

Action Type Old Value New Value Added Translation Title: panel de Ctrlpanel-gg, Description: CtrlPanel es un software de facturación de código abierto para proveedores de alojamiento. Las versiones 1.1.1 y anteriores contienen una vulnerabilidad de Cross-Site Scripting (XSS) Almacenado que existe en la interfaz de gestión de roles de administrador. En app/Http/Controllers/Admin/RoleController.php, el método datatable() interpola $role->name y $role->color directamente en el HTML y el atributo de estilo de un elemento <span> sin sanitización, y la llamada encadenada .rawColumns(['actions', 'name']) instruye a DataTables para que renderice la columna 'name' como HTML sin procesar, omitiendo el escape automático de la salida. Un administrador con permisos de creación o edición de roles puede inyectar una carga útil como <img src=x onerror="alert('XSS_POC')"> en los campos de nombre o color, que se persiste en la base de datos y se ejecuta en el navegador de cada administrador que carga la página /admin/roles. Esto permite el secuestro de sesión mediante el robo de cookies, la recolección de credenciales a través de avisos de inicio de sesión falsos o keyloggers, la escalada de privilegios lateral al realizar acciones de administrador en nombre de las víctimas, y una puerta trasera persistente que se vuelve a ejecutar en cada carga de página hasta que se elimina el registro de rol malicioso. Este problema ha sido resuelto en la versión 1.2.0. -
