CVE-2026-8603

Estado: AnalizadaAlta (8.7)—

In ScadaBR version 1.2.0, an OS Command Injection vulnerability could allow an attacker to execute commands as root on the SCADA system.

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 con PR:L indica servicio remoto que requiere autenticación previa. CWE-78 (command injection) permite T1059. La ejecución como root implica T1068 como impacto secundario.

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.
