How to Fix CVE-2020-10721

To remediate this vulnerability, upgrade all affected fabric8-maven-plugin 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.fabric8:fabric8-maven-plugin fixed: Latest secure release 
<dependency>
    <groupId>io.fabric8</groupId>
    <artifactId>fabric8-maven-plugin</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.fabric8

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-10721, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.fabric8

Analyze the terminal output to locate any version of fabric8-maven-plugin 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.fabric8 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 fabric8-maven-plugin, 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

A flaw was found in the fabric8-maven-plugin 4.0.0 and later. When using a wildfly-swarm or thorntail custom configuration, a malicious YAML configuration file on the local machine executing the maven plug-in could allow for deserialization of untrusted data resulting in arbitrary code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. The fabric8-maven-plugin has been superseded by the Eclipse project JKube and the recommendation is migrating users of the fabric8-maven-plugin to Eclipse Jkube >= 1.0.0
