How to Fix CVE-2019-10417

To remediate this vulnerability, upgrade all affected Kubernetes pipeline steps 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.pipeline:kubernetes-pipeline-steps fixed: Latest secure release 
<dependency>
    <groupId>io.fabric8.pipeline</groupId>
    <artifactId>kubernetes-pipeline-steps</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.pipeline

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-10417, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.fabric8.pipeline

Analyze the terminal output to locate any version of Kubernetes pipeline steps 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.pipeline 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-183: Permissive List of Allowed Inputs, where the product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are explicitly allowed by policy because the inputs are assumed to be safe, but the list is too permissive - that is, it allows an input that is unsafe, leading to resultant weaknesses. In Kubernetes pipeline steps, 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

Jenkins Kubernetes :: Pipeline :: Kubernetes Steps Plugin provides a custom whitelist for script security that allowed attackers to invoke arbitrary methods, bypassing typical sandbox protection.
