      "value": "Improper Input Validation, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel DNS component.\n\nThe camel-dns producers read DNS operation parameters - the resolver to query, the name or domain to look up, the record type and class, and the search term - from Exchange message headers whose constant values (DnsConstants.DNS_SERVER, DNS_NAME, DNS_DOMAIN, DNS_TYPE, DNS_CLASS, TERM) were the plain strings dns.server, dns.name, dns.domain, dns.type, dns.class and term. Because these names do not start with the Camel / camel prefix, HttpHeaderFilterStrategy - which blocks only the Camel header namespace on the HTTP boundary - let them pass from an inbound HTTP request straight into the Exchange. In a route that bridges an HTTP consumer (for example platform-http) into a dns: producer, any HTTP client could therefore set the dns.server header to make the dig producer build a SimpleResolver pointing at an attacker-controlled DNS server - a server-side request forgery via DNS, through which the attacker observes the queried name and can return poisoned responses - and set the dns.name / dns.domain headers to resolve arbitrary internal hostnames, disclosing whether they exist (internal network reconnaissance). No credentials are required when the bridging consumer is unauthenticated.\nThis issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0.\n\nUsers are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. After upgrading, routes that drive DNS operations via the raw header names must use CamelDnsServer / CamelDnsName / CamelDnsDomain / CamelDnsType / CamelDnsClass / CamelDnsTerm instead of the dns.* / term names. For deployments that cannot upgrade immediately, strip the dns.* and term headers from any untrusted ingress before the dns: producer, and set the DNS server and lookup parameters from a trusted source in the route."

      "value": "Validación de entrada incorrecta, vulnerabilidad de falsificación de petición del lado del servidor (SSRF) en el componente DNS de Apache Camel.\n\nLos productores de camel-dns leen los parámetros de operación DNS - el resolvedor a consultar, el nombre o dominio a buscar, el tipo y la clase de registro, y el término de búsqueda - de los encabezados de mensajes de Exchange cuyos valores constantes (DnsConstants.DNS_SERVER, DNS_NAME, DNS_DOMAIN, DNS_TYPE, DNS_CLASS, TERM) eran las cadenas simples dns.server, dns.name, dns.domain, dns.type, dns.class y term. Debido a que estos nombres no comienzan con el prefijo Camel / camel, HttpHeaderFilterStrategy - que bloquea solo el espacio de nombres del encabezado Camel en el límite HTTP - los dejó pasar de una petición HTTP entrante directamente al Exchange. En una ruta que conecta un consumidor HTTP (por ejemplo, platform-http) con un productor dns:, cualquier cliente HTTP podría, por lo tanto, establecer el encabezado dns.server para hacer que el productor dig construya un SimpleResolver que apunte a un servidor DNS controlado por un atacante - una falsificación de petición del lado del servidor a través de DNS, mediante la cual el atacante observa el nombre consultado y puede devolver respuestas envenenadas - y establecer los encabezados dns.name / dns.domain para resolver nombres de host internos arbitrarios, revelando si existen (reconocimiento de red interno). No se requieren credenciales cuando el consumidor de conexión no está autenticado.\nEste problema afecta a Apache Camel: desde 4.0.0 antes de 4.14.8, desde 4.15.0 antes de 4.18.3, desde 4.19.0 antes de 4.21.0.\n\nSe recomienda a los usuarios actualizar a la versión 4.21.0, que corrige el problema. Si los usuarios están en la rama de versiones LTS 4.14.x, se sugiere que actualicen a 4.14.8. Si los usuarios están en la rama de versiones 4.18.x, se sugiere que actualicen a 4.18.3. Después de actualizar, las rutas que impulsan las operaciones DNS a través de los nombres de encabezado sin procesar deben usar CamelDnsServer / CamelDnsName / CamelDnsDomain / CamelDnsType / CamelDnsClass / CamelDnsTerm en lugar de los nombres dns.* / term. Para implementaciones que no pueden actualizarse inmediatamente, elimine los encabezados dns.* y term de cualquier entrada no confiable antes del productor dns:, y establezca el servidor DNS y los parámetros de búsqueda desde una fuente confiable en la ruta."
