      "value": "Apache NiFi 0.0.1 through 2.9.0 support building qualified URLs from one of several HTTP request headers that provide an alternative to the standard Host header without validating the values provided. Apache NiFi 1.6.0 introduced a configurable application property to restrict values provided in the HTTP Host header, but did not apply the validation to alternative Proxy and Forwarded headers. The absence of proxy host header validation allowed a client to instruct Apache NiFi web services to construct invalid qualified URLs for redirection or data references. Upgrading to Apache NiFi 2.10.0 is the recommended mitigation, which implements validation for the X-ProxyHost and X-Forwarded-Host HTTP request headers based on the nifi.web.proxy.host property. Enabling header validation requires configuring the application with HTTPS. Reverse proxy servers in front of Apache NiFi are responsible for filtering input request headers and providing allowed values to the application."

      "value": "Apache NiFi 0.0.1 hasta 2.9.0 permiten construir URLs cualificadas a partir de uno de varios encabezados de solicitud HTTP que proporcionan una alternativa al encabezado Host estándar sin validar los valores proporcionados. Apache NiFi 1.6.0 introdujo una propiedad de aplicación configurable para restringir los valores proporcionados en el encabezado HTTP Host, pero no aplicó la validación a los encabezados alternativos Proxy y Forwarded. La ausencia de validación del encabezado de host proxy permitió a un cliente instruir a los servicios web de Apache NiFi para construir URLs cualificadas inválidas para redirección o referencias de datos. La actualización a Apache NiFi 2.10.0 es la mitigación recomendada, que implementa la validación para los encabezados de solicitud HTTP X-ProxyHost y X-Forwarded-Host basada en la propiedad nifi.web.proxy.host. Habilitar la validación de encabezados requiere configurar la aplicación con HTTPS. Los servidores proxy inverso delante de Apache NiFi son responsables de filtrar los encabezados de solicitud de entrada y proporcionar valores permitidos a la aplicación."
