FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Version 1.3.0 has an authorization bypass in the /api/getTagValue endpoint allows unauthenticated access to tag values when the referenced script does not exist. Version 1.3.1 patches the issue.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/AC:L/PR:N/UI:N indica acceso remoto sin autenticación a endpoint web expuesto (/api/getTagValue). Bypass de autorización expone valores de etiquetas (tags) SCADA sin credenciales válidas.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
