CVE-2016-6812

Estado: ModificadaMedia (6.1)—💥 PoC

El módulo de transporte HTTP en Apache CXF anterior a su versión 3.0.12 y en versiones 3.1.x anteriores a 3.1.9 utiliza FormattedServiceListWriter para proporcionar una página HTML que enumera los nombres y URL absolutas de endpoints de servicio disponibles. El módulo calcula la URL base empleando el HttpServletRequest actual. La URL base calculada es empleada por FormattedServiceListWritter para construir las URL absolutas de los endpoints de servicio. Si los parámetros matriz inesperados se han inyectado en la URL de petición, esos parámetros matriz volverán al cliente en la página de lista de servicios, lo que representa un riesgo de XSS para el cliente.

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).

💥 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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
