Description
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Netty HTTP component.
The camel-netty-http HTTP server consumer exposes a muteException option that controls what is returned to the client when a route processing error occurs. This option defaulted to false because the backing field was an uninitialised primitive boolean (Java's default of false), whereas the other Camel HTTP server components (camel-http / camel-jetty / camel-servlet and camel-platform-http) default it to true. With muteException=false, when a request triggers an exception during route processing the consumer writes the full Throwable stack trace into the HTTP response body as text/plain (via DefaultNettyHttpBinding) instead of returning an empty body. Any unauthenticated client that can reach the endpoint and cause a processing error - for example by sending a malformed request body, an invalid parameter, or otherwise triggering a route-internal failure - therefore receives a complete Java stack trace. Such a stack trace can disclose sensitive internal information, including credentials embedded in exception messages, internal host names and IP addresses, filesystem paths, dependency and version details, database and class names, and the application's internal structure, which an attacker can use to plan further attacks.
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. For deployments that cannot upgrade immediately, set muteException=true explicitly on the camel-netty-http consumer (for example netty-http: http://0.0.0.0:8080/api?muteException=true , or globally via the camel.component.netty-http.configuration.mute-exception=true property), so that processing errors no longer return the stack trace to the client.

Title: HTTP Netty de Apache Camel, Description: Vulnerabilidad relacionada con la generación de mensajes de error que contienen información confidencial en el componente HTTP Netty de Apache Camel. El consumidor del servidor HTTP camel-netty-http expone una opción denominada muteException que controla lo que se devuelve al cliente cuando se produce un error en el procesamiento de una ruta. Esta opción tenía como valor predeterminado false porque el campo subyacente era un valor booleano primitivo no inicializado (el valor predeterminado de Java es false), mientras que los demás componentes del servidor HTTP de Camel (camel-http, camel-jetty, camel-servlet y camel-platform-http) lo establecen por defecto en true. Con muteException=false, cuando una solicitud provoca una excepción durante el procesamiento de la ruta, el consumidor escribe el seguimiento completo de la pila de Throwable en el cuerpo de la respuesta HTTP como text/plain (a través de DefaultNettyHttpBinding), en lugar de devolver un cuerpo vacío. Cualquier cliente no autenticado que pueda acceder al punto final y provocar un error de procesamiento —por ejemplo, enviando un cuerpo de solicitud mal formado, un parámetro no válido o provocando de cualquier otra forma un fallo interno de la ruta— recibirá, por lo tanto, un seguimiento completo de la pila de Java. Dicha traza de pila puede revelar información interna confidencial, incluidas credenciales incrustadas en los mensajes de excepción, nombres de host internos y direcciones IP, rutas del sistema de archivos, detalles de dependencias y versiones, nombres de bases de datos y de clases, y la estructura interna de la aplicación, que un atacante puede utilizar para planear nuevos ataques. 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 corrige el problema. Si los usuarios utilizan las versiones LTS de la rama 4.14.x, se les sugiere que actu
