CVE-2019-6833
Estado: ModificadaMedia (6.5)—
A CWE-754 – Improper Check for Unusual or Exceptional Conditions vulnerability exists in Magelis HMI Panels (all versions of - HMIGTO, HMISTO, XBTGH, HMIGTU, HMIGTUX, HMISCU, HMISTU, XBTGT, XBTGT, HMIGXO, HMIGXU), which could cause a temporary freeze of the HMI when a high rate of frames is received. When the attack stops, the buffered commands are processed by the HMI panel.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
- Puntuación base: 6.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.05%
- Percentil entre todas las CVEs puntuadas: 63
- Fecha de la puntuación: 7/10/2026
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).
