How to Fix CVE-2020-2239

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

org.jenkins-ci.plugins:Parameterized-Remote-Trigger fixed: 3.1.4 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>Parameterized-Remote-Trigger</artifactId>
    <version>3.1.4</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=org.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-2239, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Parameterized Remote Trigger in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.4), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.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-311: Missing Encryption of Sensitive Data, where the product does not encrypt sensitive or critical information before storage or transmission. In Parameterized Remote Trigger, 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

Parameterized Remote Trigger Plugin 3.1.3 and earlier stores a secret unencrypted in its global configuration file `org.jenkinsci.plugins.ParameterizedRemoteTrigger.RemoteBuildConfiguration.xml` on the Jenkins controller as part of its configuration. This secret can be viewed by attackers with access to the Jenkins controller file system. Parameterized Remote Trigger Plugin 3.1.4 stores the secret encrypted once its configuration is saved again.
