How to Fix CVE-2020-2211

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

com.elasticbox.jenkins-ci.plugins:kubernetes-ci fixed: Latest secure release 
<dependency>
    <groupId>com.elasticbox.jenkins-ci.plugins</groupId>
    <artifactId>kubernetes-ci</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=com.elasticbox.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-2211, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.elasticbox.jenkins-ci.plugins

Analyze the terminal output to locate any version of Kubernetes ci 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=com.elasticbox.jenkins-ci.plugins 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 Kubernetes ci, 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

ElasticBox Jenkins Kubernetes CI/CD Plugin 1.3 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to provide YAML input files to ElasticBox Jenkins Kubernetes CI/CD Plugin’s build step.
