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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

Vector AV:N/AC:L sin autenticación (PR:N, UI:N) indica explotación remota directa (T1190). CWE-284 (control de acceso impropio) permite obtener privilegios o lectura de datos sensibles, derivando en T1078.002 (cuentas comprometidas), T1005 (acceso a datos) y T1547.014 (persistencia mediante privileg

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.
