FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, the TDengine DAQ storage connector's escapeTdString function in server/runtime/storage/tdengine/index.js doubles single quotes but does not escape backslashes. A remote unauthenticated attacker can submit a crafted sids tag identifier through GET /api/daq or the Socket.IO DAQ_QUERY event so TDengine interprets the backslash and quote sequence as SQL syntax. The injected query can return every row from fuxa.meters, exposing historical PLC tag values, device identifiers, and device names even when FUXA authentication is enabled. This issue is fixed in version 1.3.2.
