How to Fix CVE-2022-43402

To remediate this vulnerability, upgrade all affected Jenkins Pipeline 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.workflow:workflow-cps fixed: 2803.v1a_f77ffcc773 
<dependency>
    <groupId>org.jenkins-ci.plugins.workflow</groupId>
    <artifactId>workflow-cps</artifactId>
    <version>2803.v1a_f77ffcc773</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.workflow

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-43402, inspect your build dependencies using the Maven Dependency Plugin:

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

Analyze the terminal output to locate any version of Jenkins Pipeline in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2803.v1a_f77ffcc773), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jenkins-ci.plugins.workflow 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-693: Protection Mechanism Failure, where the product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. In Jenkins Pipeline, 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

A sandbox bypass vulnerability involving various casts performed implicitly by the Groovy language runtime in Jenkins Pipeline: Groovy Plugin 2802.v5ea_628154b_c2 and earlier allows attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. Pipeline: Groovy Plugin 2803.v1a_f77ffcc773 intercepts Groovy casts performed implicitly by the Groovy language runtime
