How to Fix CVE-2017-5643

To remediate this vulnerability, upgrade all affected Camel core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

org.apache.camel:camel-core fixed: 2.17.6 
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-core</artifactId>
    <version>2.17.6</version>
</dependency>
org.apache.camel:camel-core fixed: 2.18.2 
<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-core</artifactId>
    <version>2.18.2</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.apache.camel

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2017-5643, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.camel

Analyze the terminal output to locate any version of Camel core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.17.6), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.camel command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-918: Server-Side Request Forgery (SSRF), where the web server receives a url or similar request from an upstream component and retrieves the contents of this url, but it does not sufficiently ensure that the request is being sent to the expected destination. In Camel core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Description: The Validation Component of Apache Camel evaluates DTD headers of XML stream sources, although a validation against XML schemas (XSD) is executed. Remote attackers can use this feature to make Server-Side Request Forgery (SSRF) attacks by sending XML documents with remote DTDs URLs or XML External Entities (XXE). The vulnerability is not given for SAX or StAX sources. Mitigation: 2.17.x users should upgrade to 2.17.6, 2.18.x users should upgrade to 2.18.3. The JIRA tickets https://issues.apache.org/jira/browse/CAMEL-10894 refers to the various commits that resolved the issue, and have more details.
