Summary

Apache Camel from 4.0.0 before 4.18.5 and from 4.19.0 before 4.22.1 contains a generation of error message containing sensitive information flaw (CWE-209) in its Knative component. When exchange processing failed on the consumer side, the Knative HTTP consumer returned the exception class name, message and stack trace to the caller as the response body. A remote, unauthenticated attacker can trigger a failure and read internal details such as class and package names and host names.

Description from the CNA

Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel Knative component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When processing of an exchange failed on the consumer side, the Knative HTTP consumer wrote the resulting exception back to the remote caller as the response body, including its class name, message and stack trace. An external sender could therefore provoke a failure and read internal detail about the deployment: class and package names, file system or host names carried in exception messages, and the shape of the route. That detail is useful for building a more targeted attack, and where an exception message embeds configuration or connection strings it is disclosure in its own right. camel-knative was the remaining HTTP-family consumer that had not been aligned with the muteException behaviour established for the other HTTP consumers by CAMEL-23651. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. The consumer now honours a muteException option that defaults to true, so a route failure returns an empty body with the error status rather than the exception. Set muteException=false to restore the previous output. For deployments that cannot upgrade immediately, add an onException handler that sets the response body explicitly, so that the framework never writes the exception back to the caller.

Remediation

Upgrade Apache Camel to 4.18.5 on the 4.18.x LTS stream, to 4.22.1 on the 4.22.x LTS stream, or to 4.23.0. Red Hat lists OpenShift Serverless and Red Hat build of Apache Camel for Spring Boot 4 as affected without a fix plan. Until the upgrade is applied, add an onException handler that sets the response body explicitly so the framework never writes the exception to the caller.
