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:4.0/AV:N/AC:L/PR:N/UI:N indica red sin autenticación. CWE-434 (upload de ficheros) + endpoint PHP expuesto + descripción explícita de RCE vía upload de PHP confirman T1190. Impacto web shell (T1505.003) por upload de PHP; ejecución de código arbitrario (T1059) secundaria.

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.
