How to Fix CVE-2022-42468

To remediate this vulnerability, upgrade all affected Flume jms source 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.flume.flume-ng-sources:flume-jms-source fixed: 1.11.0 
<dependency>
    <groupId>org.apache.flume.flume-ng-sources</groupId>
    <artifactId>flume-jms-source</artifactId>
    <version>1.11.0</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.flume.flume-ng-sources

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-42468, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.flume.flume-ng-sources

Analyze the terminal output to locate any version of Flume jms source in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.11.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.flume.flume-ng-sources 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Flume jms source, 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

Flume’s JMSSource class can be configured with a providerUrl parameter. A JNDI lookup is performed on this name without performing validation. This could result in untrusted data being deserialized, leading to remote code execution (RCE) attack when a configuration uses a JMS Source with an unsafe providerURL. This issue is fixed in version 1.11.0.
