How to Fix CVE-2020-2183

To remediate this vulnerability, upgrade all affected Copyartifact 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:copyartifact fixed: 1.44 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>copyartifact</artifactId>
    <version>1.44</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-2020-2183, 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 Copyartifact in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.44), 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-285: Improper Authorization, where the product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. In Copyartifact, 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

Copy Artifact Plugin 1.43.1 and earlier performs improper permission checks when determining whether a build can copy artifacts from another project build. This allows attackers, usually with Job/Configure permission, to configure jobs to copy artifacts from jobs they have no permission to access. Copy Artifact Plugin 1.44 now properly performs permission checks when copying artifacts. When updating the plugin from a previous version, the previous behavior is retained (\"Migration mode\"). To enable the additional protections, switch to the new \"Production mode\". Doing so may cause existing jobs to fail to copy artifacts. For more information see the [plugin documentation](https://github.com/jenkinsci/copyartifact-plugin).
