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/PR:L/AC:L indica acceso remoto con privilegios bajos; Editor sobreescribe dashboard ajena para escalada. T1210 (explotación de servicios remotos con privilegios). T1078 (obtención de permisos elevados en dashboard específico); T1098 (modificación de cuenta/permisos mediante sobrescritura.

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.
