How the CVE Works:
The vulnerability exists in Apache Camel’s default header filtering mechanism, which fails to properly block maliciously crafted headers due to insufficient case-sensitive checks. Attackers can inject custom headers (e.g., cAmelFoo) to bypass filters that only block exact-case variants like “Camel” or “camel.” This allows manipulation of components like camel-bean, enabling unauthorized method execution, or camel-jms, rerouting messages to unintended queues. The exploit requires HTTP header injection, affecting components such as camel-jetty, camel-servlet, and `camel-netty-http` when exposed to untrusted inputs.
DailyCVE Form:
Platform: Apache Camel
Version: 3.10.0-3.22.3, 4.8.0-4.8.4, 4.10.0-4.10.1
Vulnerability: Header Injection
Severity: Critical
Date: 2025-03-09
Prediction: Patch by 2025-03-20
What Undercode Say:
Check vulnerable Camel versions:
camel-core -v | grep -E "3.10.0|4.8.0|4.10.0"
Mitigation via route header stripping:
from("direct:input").removeHeaders("cAmel").to("bean:target");
How Exploit:
- Attacker sends HTTP request with malicious header:
cAmelMethod=maliciousMethod.
2. `camel-bean` processes the header, invoking `maliciousMethod` instead of the intended method.
Protection from this CVE:
- Upgrade to Camel 3.22.4, 4.8.5, or 4.10.2.
- Globally filter headers:
camelContext.setHeaderFilterStrategy(new StrictCaseSensitiveFilter()).
Impact:
- Unauthorized bean method execution.
- Message queue hijacking.
- Remote code execution (if beans handle sensitive logic).
