CVE-2026-67440

FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the DEVICE_BROWSE, DEVICE_NODE_ATTRIBUTE, HOST_INTERFACES, and DEVICE_TAGS_REQUEST handlers in server/runtime/index.js return device-discovery, node-attribute, host-network-interface, and device-tag metadata without isSocketAdminAuthorized when secureEnabled is true. A remote unauthenticated or guest user can invoke these metadata-oriented Socket.IO events and collect system-discovery information that is not required for normal public HMI viewing, while ordinary device status, value, alarm, and dashboard events remain intentionally public. This issue is fixed in version 1.3.3.

Summary		(es) FUXA es un software de visualización de procesos basado en web (SCADA/HMI/Dashboard). En 1.3.2 y anteriores, los manejadores DEVICE_BROWSE, DEVICE_NODE_ATTRIBUTE, HOST_INTERFACES y DEVICE_TAGS_REQUEST en servidor/runtime/index.js devuelven metadatos de descubrimiento de dispositivos, atributos de nodo, interfaz de red de host y etiquetas de dispositivo sin isSocketAdminAuthorized cuando secureEnabled es verdadero. Un usuario remoto no autenticado o invitado puede invocar estos eventos Socket.IO orientados a metadatos y recopilar información de descubrimiento del sistema que no es necesaria para la visualización HMI pública normal, mientras que los eventos ordinarios de estado de dispositivo, valor, alarma y panel de control permanecen intencionalmente públicos. Este problema está solucionado en la versión 1.3.3.
