How to Fix CVE-2022-34181

To remediate this vulnerability, upgrade all affected Xunit 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:xunit fixed: 3.1.0 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>xunit</artifactId>
    <version>3.1.0</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=org.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-34181, 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 Xunit in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.1.0), 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-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 Xunit, 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

xUnit Plugin 3.0.8 and earlier implements an agent-to-controller message that creates a user-specified directory if it doesn’t exist, and parsing files inside it as test results. This allows attackers able to control agent processes to create an arbitrary directory on the Jenkins controller or to obtain test results from existing files in an attacker-specified directory. xUnit Plugin 3.1.0 changes the message type from agent-to-controller to controller-to-agent, preventing execution on the controller.
