Description
Improper Input Validation, Exposure of Sensitive Information to an Unauthorized Actor, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel in Atmosphere Websocket Component.
The camel-atmosphere-websocket consumer mapped inbound WebSocket query parameters into the Camel Exchange header map without applying any HeaderFilterStrategy (WebsocketConsumer.sendEventNotification() iterates the query-string map collected in WebsocketConsumer.service() and copies each entry into the Exchange). Because nothing blocked the Camel header namespace, a client connecting to the WebSocket endpoint could set Camel-internal control headers - including CamelHttpUri (Exchange.HTTP_URI) - simply by supplying them as query parameters. In a route where the WebSocket consumer feeds a downstream HTTP producer, the injected CamelHttpUri redirects the server-side HTTP request to an attacker-chosen destination (server-side request forgery - for example to an internal service or a cloud metadata endpoint). In addition, the HTTP producer resolves Camel property placeholders on the resulting (attacker-controlled) URI, so placeholders embedded in the injected value - such as an environment-variable reference, an application property, or a vault reference - are resolved to their real values and sent to the attacker, disclosing environment variables, application properties and vault secrets. When the WebSocket endpoint is exposed without authentication, this is reachable by an unauthenticated remote attacker.
This 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.
Users 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. The fix makes the consumer apply the HeaderFilterStrategy it already inherits from the HTTP/servlet stack, filtering the Camel header namespace case-insensitively on inbound mapping, so externally-supplied Camel* / camel* headers are no longer copied into the Exchange. For deployments that cannot upgrade immediately, strip the Camel control headers from the inbound message before they reach any downstream producer (for example removeHeaders('Camel*') and removeHeaders('camel*') at the start of the route), require authentication on the WebSocket endpoint, and avoid bridging an untrusted consumer directly into an HTTP producer whose target URI can be driven from message headers.

Title: Atmosphere WebSocket, Description: Validación incorrecta de entradas, exposición de información confidencial a un agente no autorizado y vulnerabilidad de falsificación de solicitudes del lado del servidor (SSRF) en Apache Camel, en el componente Atmosphere WebSocket. El consumidor camel-atmosphere-websocket asignaba los parámetros de consulta de WebSocket entrantes al mapa de encabezados de Camel Exchange sin aplicar ninguna HeaderFilterStrategy (WebsocketConsumer.sendEventNotification() recorre el mapa de cadenas de consulta recopilado en WebsocketConsumer.service() y copia cada entrada en el Exchange). Dado que nada bloqueaba el espacio de nombres de encabezados de Camel, un cliente que se conectara al punto final de WebSocket podía establecer encabezados de control internos de Camel —incluido CamelHttpUri (Exchange.HTTP_URI)— simplemente proporcionándolos como parámetros de consulta. En una ruta en la que el consumidor WebSocket alimenta a un productor HTTP posterior, el CamelHttpUri inyectado redirige la solicitud HTTP del lado del servidor a un destino elegido por el atacante (falsificación de solicitudes del lado del servidor; por ejemplo, a un servicio interno o a un punto final de metadatos en la nube). Además, el productor HTTP resuelve los marcadores de posición de propiedades de Camel en la URI resultante (controlada por el atacante), por lo que los marcadores de posición incrustados en el valor inyectado —como una referencia a una variable de entorno, una propiedad de la aplicación o una referencia al almacén de secretos— se resuelven a sus valores reales y se envían al atacante, revelando variables de entorno, propiedades de la aplicación y secretos del almacén. Cuando el punto final de WebSocket está expuesto sin autenticación, un atacante remoto no autenticado puede acceder a él. Este problema afecta a Apache Camel: desde la versión 4.0.0 hasta la 4.14.8, desde la 4.15.0 hasta la 4.18.3 y desde la 4.19.0 hasta la 4.21.0. Se recomienda a los usuarios que actualicen a la versión 4.21.0, que c
