Descriptions

In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), HTTP/0.9 is handled poorly. An HTTP/1 style request line (i.e. method space URI space version) that declares a version of HTTP/0.9 was accepted and treated as a 0.9 request. If deployed behind an intermediary that also accepted and passed through the 0.9 version (but did not act on it), then the response sent could be interpreted by the intermediary as HTTP/1 headers. This could be used to poison the cache if the server allowed the origin client to generate arbitrary content in the response.

En Eclipse Jetty, en versiones 9.2.x y anteriores, versiones 9.3.x (todas las configuraciones) y versiones 9.4.x (configuración personalizada con el cumplimiento RFC2616 habilitado), HTTP/0.9 se gestiona de forma incorrecta. Una línea de petición de estilo HTTP/1 (p.ej., método espacio URI espacio versión) que declara una versión de HTTP/0.9 se aceptó y trató como petición 0.9. Si se implementa tras un intermediario que también aceptó y pasó la versión 0.9 (pero no actuó en consecuencia), la respuesta enviada podría ser interpretada por el intermediario como cabeceras HTTP/1. Esto podría utilizarse para envenenar la caché si el servidor permite que el cliente de origen genere contenido arbitrario en la respuesta.
