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.

Vulnerabilidad de traversal de directorios en aplicación web expuesta (AV:N, PR:N, UI:N) que permite atacante no autenticado cambiar directorio de plantillas causando DoS. CWE-22 confirma path traversal; impacto es degradación de servicio (A:H) e imposibilidad de lectura de datos de configuración.

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.
