In versions prior to 1.9.0, a user supplied `X-Forwarded-Host` header can be used to perform cache poisoning of a cache fronting a Ratpack server if the cache key does not include the `X-Forwarded-Host` header as a cache key. Users are only vulnerable if they do not configure a custom `PublicAddress` instance. For versions prior to 1.9.0, by default, Ratpack utilizes an inferring version of `PublicAddress` which is vulnerable. This can be used to perform redirect cache poisoning where an attacker can force a cached redirect to redirect to their site instead of the intended redirect location. The vulnerability was patched in Ratpack 1.9.0. As a workaround, ensure that `ServerConfigBuilder::publicAddress` correctly configures the server in production."}, {"lang": "es", "value": "Ratpack es un kit de herramientas para crear aplicaciones web. En versiones anteriores a 1.9.0, una cabecera \"X-Forwarded-Host\" suministrada por el usuario puede ser usada para llevar a cabo el envenenamiento de la cach\u00e9 de un servidor Ratpack si la clave de la cach\u00e9 no incluye la cabecera \"X-Forwarded-Host\" como clave de la cach\u00e9. Unos usuarios s\u00f3lo son vulnerables si no configuran una instancia personalizada de \"PublicAddress\". Para versiones anteriores a 1.9.0, por defecto, Ratpack usa una versi\u00f3n inferida de \"PublicAddress\" que es vulnerable. Esto puede ser usado para llevar a cabo el envenenamiento de la cach\u00e9 de redireccionamiento, donde un atacante puede forzar un redireccionamiento en cach\u00e9 para redirigir a su sitio en lugar de la ubicaci\u00f3n de redireccionamiento prevista.
