Descriptions

Apache CXF supports sending and receiving attachments via either the JAX-WS or JAX-RS specifications. It is possible to craft a message attachment header that could lead to a Denial of Service (DoS) attack on a CXF web service provider. Both JAX-WS and JAX-RS services are vulnerable to this attack. From Apache CXF 3.2.1 and 3.1.14, message attachment headers that are greater than 300 characters will be rejected by default. This value is configurable via the property "attachment-max-header-size".

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".
