      "value": "FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. In 1.3.2 and earlier, the allowDashboard authorization gate in server/integrations/node-red/index.js calls authJwt.verify for /nodered without inspecting the decoded identity. When nodeRedEnabled is true, secureEnabled is true, and nodeRedAuthMode is secure, a remote unauthenticated attacker can obtain a signed guest token from POST /api/heartbeat and use it to access the RED.httpAdmin editor and flow deployment API. Because the Node-RED configuration has no second adminAuth gate, the attacker can deploy function nodes or invoke fuxa.runScript and runtime.scriptsMgr.runScript, gaining control of FUXA project data, configuration, scripts, filesystem-capable runtime helpers, and potentially operating-system commands when nodeRedUnsafeModules is enabled. This issue is fixed in version 1.3.3."

      "value": "FUXA es un software de Visualización de Procesos (SCADA/HMI/Dashboard) basado en web. En 1.3.2 y versiones anteriores, la puerta de autorización allowDashboard en server/integrations/node-red/index.js llama a authJwt.verify para /nodered sin inspeccionar la identidad decodificada. Cuando nodeRedEnabled es verdadero, secureEnabled es verdadero y nodeRedAuthMode es seguro, un atacante remoto no autenticado puede obtener un token de invitado firmado de POST /api/heartbeat y usarlo para acceder al editor RED.httpAdmin y a la API de despliegue de flujos. Debido a que la configuración de Node-RED no tiene una segunda puerta adminAuth, el atacante puede desplegar nodos de función o invocar fuxa.runScript y runtime.scriptsMgr.runScript, obteniendo control de los datos del proyecto FUXA, configuración, scripts, ayudantes de tiempo de ejecución con capacidad de sistema de archivos y potencialmente comandos del sistema operativo cuando nodeRedUnsafeModules está habilitado. Este problema está solucionado en la versión 1.3.3."
