AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Network-reachable endpoint, no auth required, no user interaction; confidentiality rated Low rather than High because disclosure is conditional on exception verbosity and what credentials appear in stack traces.

Stack trace disclosure in Apache Camel's camel-netty-http component (versions 4.0.0-4.21.0 across three release streams) exposes full Java Throwable stack traces to unauthenticated HTTP clients whenever a route processing error occurs under the default configuration. The root cause is an insecure default: the muteException option backed by an uninitialized Java primitive boolean defaulted to false in camel-netty-http while all other Camel HTTP server components (camel-http, camel-jetty, camel-servlet, camel-platform-http) correctly default it to true. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target application uses the camel-netty-http component specifically - not camel-http, camel-jetty, camel-servlet, or camel-platform-http, which default muteException to true and are unaffected. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The real-world risk is moderate and primarily serves as an enablement primitive for follow-on attacks rather than a standalone critical flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies an internet- or network-exposed Apache Camel endpoint backed by camel-netty-http - discoverable via HTTP fingerprinting or known application topology. The attacker sends a deliberately malformed HTTP request (invalid content-type, malformed body, out-of-range parameter) that triggers an uncaught exception in the Camel route. … |
| Remediation | The primary fix is to upgrade to Apache Camel 4.14.8 (for users on the 4.14.x LTS stream), 4.18.3 (for users on the 4.18.x stream), or 4.21.0 (current), all of which flip the muteException default to true at both component and endpoint levels. … Detailed patch versions, workarounds, and compensating controls in full report. |
