How to Fix CVE-2024-36543

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

io.strimzi:strimzi fixed: Latest secure release 
<dependency>
    <groupId>io.strimzi</groupId>
    <artifactId>strimzi</artifactId>
    <version>Latest secure release</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=io.strimzi

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2024-36543, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.strimzi

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

Note: The mvn dependency:tree -Dincludes=io.strimzi 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Strimzi, 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

Incorrect access control in the Kafka Connect REST API in the STRIMZI Project 0.41.0 and earlier allows an attacker to deny the service for Kafka Mirroring, potentially mirror the topics' content to his Kafka cluster via a malicious connector (bypassing Kafka ACL if it exists), and potentially steal Kafka SASL credentials, by querying the MirrorMaker Kafka REST API.
