Low risk40th percentile - higher than 40% of all known CVEs
Summary
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Prior to 1.3.2, the escapeTdString function does not escape backslashes, allowing a remote unauthenticated attacker to inject SQL via crafted sids tag identifiers. This can expose historical PLC tag values and device names.
Risk Assessment
The risk includes exposure of sensitive industrial data, such as PLC tag values and device identifiers, even with authentication enabled.
Recommendation
Upgrade FUXA to version 1.3.2 or later, which fixes the issue by properly escaping backslashes.
Original NVD description (English source)
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.
