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.

Vector CVSS N/N/N indica exposición en red sin autenticación. CWE-94/95 (eval injection) y descripción confirman ejecución de comandos. Aunque requiere acceso al fichero de configuración, la explotación es remota (AV:N) si ese fichero es accesible vía interfaz web o API. Impacto: ejecución de comand

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.
