Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.44%
Percentil entre todas las CVEs puntuadas: 36
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1190 Exploit Public-Facing Applicationinitial access95 %
Impacto principalT1078 Valid Accountsstealth · persistence · privilege escalation · initial access90 %
Impacto secundarioT1005 Data from Local Systemcollection85 %

Vector AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). Falta de validación de acceso permite lectura no autorizada de documentos (T1005) e impersonación/acceso como usuario válido (T1078).

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.
