Description
Generation of Error Message Containing Sensitive Information vulnerability in Apache Camel CXF component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. When a route behind a CXF SOAP consumer failed with an exception the service contract does not declare, the exception was described back to the SOAP client in the fault: CXF copies the message into the SOAP faultstring, and can be configured to place the stack trace in the fault detail. An external caller able to provoke a failure could therefore read internal detail about the deployment - class and package names, and whatever the exception message carries. Declared faults, annotated @WebFault, are a different matter: those are part of the published contract that clients are written against, and suppressing them would break the service rather than protect anything. 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. A muteException consumer option, defaulting to true, replaces an undeclared route failure with a generic fault carrying no class name, message or stack trace. Faults the contract declares are reported exactly as before. Set muteException=false to restore the previous output. For deployments that cannot upgrade immediately, declare the exceptions the service is allowed to report and map every other failure onto one of them in an onException handler, so no undeclared exception reaches the fault.

| Decided by | Medium or Low severity, no CISA or VulnCheck KEV listing, no PoC clearing the evidence bar, no CISA verdict, no Oracle advisory |
|---|---|
| Finding | This CVE is MEDIUM severity, is not listed in CISA KEV or VulnCheck KEV, has no public exploit or PoC in any indexed source, carries no CISA Vulnrichment finding of a demonstrated exploit, and is not part of an Oracle Critical Patch Update. None of the signals that would put it in front of an engineer is present, and the volume of CVEs below that bar is too great to take one at a time, so no rule is written for it. This is a decision about what we act on, not a finding that the CVE is harmless — a patch may well be derivable, and a low-severity defect can still be one link in a longer chain. |
