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:3.1 de acceso en red sin autenticación (AV:N/PR:N/UI:N) indica T1190. CWE-693 sobre contravención de defensas sugiere acceso a datos (C:H) e integridad afectada (I:H) sin disponibilidad; impactos T1005 (lectura de datos) y T1565 (manipulación).
