Description
Improper Input Validation, Exposure of Sensitive Information to an Unauthorized Actor, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel in Iggy component.
The camel-iggy consumer mapped the user-headers of inbound Iggy messages into the Camel Exchange header map without applying any HeaderFilterStrategy (IggyFetchRecords copied the message user-headers straight into the Exchange). Because nothing blocked the Camel header namespace, an actor able to publish to the consumed Iggy stream/topic could set Camel-internal control headers - including CamelHttpUri (Exchange.HTTP_URI) - simply by supplying them as message user-headers. In a route where the Iggy 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.
This issue affects Apache Camel: from 4.17.0 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 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix adds a dedicated IggyHeaderFilterStrategy (and a headerFilterStrategy endpoint option) that filters 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), restrict who can publish to the consumed Iggy stream/topic, and avoid bridging an untrusted consumer directly into an HTTP producer whose target URI can be driven from message headers.

Title: Iggy, 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 Iggy. El consumidor «camel-iggy» asignaba los encabezados de usuario de los mensajes entrantes de Iggy al mapa de encabezados de Camel Exchange sin aplicar ninguna estrategia de filtrado de encabezados (HeaderFilterStrategy); IggyFetchRecords copiaba los encabezados de usuario del mensaje directamente en el Exchange. Dado que nada bloqueaba el espacio de nombres de encabezados de Camel, un actor capaz de publicar en el flujo o tema de Iggy consumido podía establecer encabezados de control internos de Camel —incluido CamelHttpUri (Exchange.HTTP_URI)— simplemente proporcionándolos como encabezados de usuario del mensaje. En una ruta en la que el consumidor de Iggy 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. Este problema afecta a Apache Camel: desde la versión 4.17.0 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 corrige el problema. Si los usuarios se encuentran en la rama de versiones 4.18.x, se les sugiere que actualicen a la 4.18.3. La corrección añade una IggyHeaderFilterStrategy específica (y una opción
