"value": "The net/http HTTP/1.1 client mishandled the case where a server responds to a request with an \"Expect: 100-continue\" header with a non-informational (200 or higher) status. This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending \"Expect: 100-continue\" requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail."

Este mal manejo podr\u00eda dejar una conexi\u00f3n de cliente en un estado no v\u00e1lido, donde la siguiente solicitud enviada a la conexi\u00f3n fallar\u00e1. Un atacante que env\u00eda una solicitud a un proxy net/http/httputil.ReverseProxy puede aprovechar este mal manejo para provocar una denegaci\u00f3n de servicio enviando solicitudes \"Esperar: 100-continuar\" que provocan una respuesta no informativa del backend. Cada una de estas solicitudes deja al proxy con una conexi\u00f3n no v\u00e1lida y provoca que falle una solicitud posterior que utiliza esa conexi\u00f3n."
