CVE-2017-12624

Estado: ModificadaMedia (5.5)—💥 PoC

Apache CXF es compatible con el envío y la recepción de archivos adjuntos mediante las especificaciones JAX-WS o JAX-RS. Es posible manipular una cabecera de adjunto de mensaje que podría conducir a un ataque de denegación de servicio (DoS) en un proveedor de servicios web de CXF. Tanto los servicios JAX-WS como JAX-RS son vulnerables a este ataque. Desde las versiones 3.2.1 y 3.1.14 de Apache CXF, la cabeceras de adjunto de mensaje de más de 300 caracteres se rechazarán por defecto. Este valor puede configurarse mediante la propiedad "attachment-max-header-size".

CVSS

Versión: 3.0
Vector: CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Puntuación base: 5.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 3.70%
Percentil entre todas las CVEs puntuadas: 89
Fecha de la puntuación: 12/10/2026

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
