Summary
FUXA: Unauthenticated Socket.IO read events
Details

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.
