Unauthenticated Remote Code Execution in FUXA via JWT Misconfiguration

Publication date: 2026-02-09

Last updated on: 2026-02-13

Assigner: GitHub, Inc.

Description
FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. An insecure default configuration in FUXA allows an unauthenticated, remote attacker to gain administrative access and execute arbitrary code on the server. This affects FUXA through version 1.2.9 when authentication is enabled, but the administrator JWT secret is not configured. This issue has been patched in FUXA version 1.2.10.

Executive Summary

This vulnerability exists in FUXA, a web-based Process Visualization software used for SCADA, HMI, and dashboards. Due to an insecure default configuration, if the administrator JWT secret is not set while authentication is enabled, an unauthenticated remote attacker can gain administrative access to the system.

Once administrative access is obtained, the attacker can execute arbitrary code on the server, potentially taking full control of the affected system.

This issue affects versions of FUXA up to 1.2.9 and has been fixed in version 1.2.10.

Impact Analysis

The vulnerability allows an unauthenticated attacker to gain administrative access and execute arbitrary code on the server running FUXA.

This can lead to full compromise of the affected system, including unauthorized control over process visualization and potentially critical industrial control systems.

Such a compromise could result in disruption of operations, data theft, manipulation of process data, or further attacks within the network.

Mitigation Strategies

To mitigate this vulnerability, upgrade FUXA to version 1.2.10 or later where the issue has been patched.

Ensure that the administrator JWT secret is properly configured to prevent unauthenticated remote administrative access.
