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.

Upload sin restricciones de ficheros (CWE-434) en plugin web expuesto permite subir web shell. AV:N/AC:H sin UI/PR indica explotación remota T1190. Impacto primario web shell (T1505.003); secundario escalada si el servidor ejecuta con privilegios elevados (S:C sugiere scope ampliado).

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.
