How to Fix CVE-2020-2320

To remediate this vulnerability, upgrade all affected Plugin management parent pom 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.jenkins.plugin-management:plugin-management-parent-pom fixed: 2.2.0 
<dependency>
    <groupId>io.jenkins.plugin-management</groupId>
    <artifactId>plugin-management-parent-pom</artifactId>
    <version>2.2.0</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.jenkins.plugin-management

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-2320, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jenkins.plugin-management

Analyze the terminal output to locate any version of Plugin management parent pom in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jenkins.plugin-management 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-494: Download of Code Without Integrity Check, where the product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code. In Plugin management parent pom, 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 Plugin Installation Manager Tool is part of the Jenkins project Docker images. As `jenkins-plugin-cli` it is used to download and install plugins even before Jenkins is running. Jenkins Plugin Installation Manager Tool 2.1.3 and earlier does not verify plugin downloads. This may allow third parties such as mirror operators to provide crafted plugin downloads. Jenkins Plugin Installation Manager Tool 2.2.0 confirms that actual checksums of downloaded plugin match the expected checksums. Docker images of Jenkins 2.269 and 2.263.1 contain Plugin Installation Manager Tool 2.2.0. Users of older Docker images can change the version they use by extending the Jenkins image and update the tool themselves with: ARG PLUGIN_CLI_URL=https://github.com/jenkinsci/plugin-installation-manager-tool/releases/download/2.2.0/jenkins-plugin-manager-2.2.0.jar RUN curl -fsSL ${PLUGIN_CLI_URL} -o /usr/lib/jenkins-plugin-manager.jar Jenkinsfile Runner [1.0-beta-22](https://github.com/jenkinsci/jenkinsfile-runner/releases/tag/1.0-beta-22) Docker images also include Plugin Installation Manager Tool 2.2.0.
