"value": "An issue was discovered in Squid before 4.13 and 5.x before 5.0.4. Due to incorrect data validation, HTTP Request Smuggling attacks may succeed against HTTP and HTTPS traffic. This leads to cache poisoning. This allows any client, including browser scripts, to bypass local security and poison the proxy cache and any downstream caches with content from an arbitrary source. When configured for relaxed header parsing (the default), Squid relays headers containing whitespace characters to upstream servers. When this occurs as a prefix to a Content-Length header, the frame length specified will be ignored by Squid (allowing for a conflicting length to be used from another Content-Length header) but relayed upstream."

"value": "Se detect\u00f3 un problema en Squid versiones anteriores a 4.13 y versiones 5.x anteriores a 5.0.4. Debido a una comprobaci\u00f3n de datos incorrecta, los ataques de Contrabando de Peticiones HTTP pueden tener \u00e9xito contra el tr\u00e1fico HTTP y HTTPS. Esto conlleva a un envenenamiento de la cach\u00e9. Esto permite a cualquier cliente, incluyendo los scripts del navegador, omitir la seguridad local y envenenar el cach\u00e9 del proxy y cualquier cach\u00e9 aguas abajo con contenido de una fuente arbitraria. Cuando es configurado para un an\u00e1lisis de encabezado relajado (el valor predeterminado), Squid transmite encabezados que contienen caracteres de espacio en blanco hacia los servidores aguas arriba. Cuando esto ocurre como un prefijo en un encabezado Content-Length, Squid ignorar\u00e1 la longitud de trama especificada (permitiendo usar una longitud conflictiva desde otro encabezado Content-Length) pero se retransmitir\u00e1 aguas arriba"
