How to Fix CVE-2020-2309

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

<dependency>
    <groupId>org.csanchez.jenkins.plugins</groupId>

</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.csanchez.jenkins.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-2309, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.csanchez.jenkins.plugins

Analyze the terminal output to locate any version of Kubernetes in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.27.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.csanchez.jenkins.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-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Kubernetes, 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 Plugin prior to 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 does not perform a permission check in an HTTP endpoint. This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability. An enumeration of credentials IDs in Kubernetes Plugin 1.27.4, 1.26.5, 1.25.4.1, and 1.21.6 requires the appropriate permissions.
