Upgrade bRPC to version 1.8.0, which fixes this issue. Download link: https://github.com/apache/brpc/releases/tag/1.8.0\n 2. Apply this patch:\u00a0 https://github.com/apache/brpc/pull/2518 \n\n"}, {"lang": "es", "value": "Vulnerabilidad de contrabando de solicitudes en el servidor HTTP en Apache bRPC 0.9.5~1.7.0 en todas las plataformas permite al atacante contrabandear solicitudes. Descripci\u00f3n de la causa de la vulnerabilidad: http_parser no cumple con la especificaci\u00f3n RFC-7230 HTTP 1.1. Escenario de ataque: si se recibe un mensaje con un campo de encabezado Transfer-Encoding y Content-Length, dicho mensaje podr\u00eda indicar un intento de realizar contrabando de solicitudes o divisi\u00f3n de respuestas. Un escenario de ataque particular es que un bRPC cre\u00f3 un servidor http en el backend que recibe solicitudes en una conexi\u00f3n persistente desde el servidor frontend que usa TE para analizar la solicitud con la l\u00f3gica de que el \"fragmento\" est\u00e1 contenido en el campo TE. En ese caso, un atacante puede introducir de contrabando una solicitud en la conexi\u00f3n con el servidor backend. Soluci\u00f3n: Puede elegir una de las siguientes soluciones: 1. Actualice bRPC a la versi\u00f3n 1.8.0, que soluciona este problema. Enlace de descarga: https://github.com/apache/brpc/releases/tag/1.8.0 2.
