How to Fix CVE-2024-34145

To remediate this vulnerability, upgrade all affected Script security 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:script-security fixed: 1336.vf33a 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>script-security</artifactId>
    <version>1336.vf33a</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-2024-34145, 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 Script security in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1336.vf33a), 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-290: Authentication Bypass by Spoofing, where this attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. In Script security, 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 Script Security Plugin provides a sandbox feature that allows low privileged users to define scripts, including Pipelines, that are generally safe to execute. Calls to code defined inside a sandboxed script are intercepted, and various allowlists are checked to determine whether the call is to be allowed. Multiple sandbox bypass vulnerabilities exist in Script Security Plugin 1335.vf07d9ce377a_e and earlier: - Crafted constructor bodies that invoke other constructors can be used to construct any subclassable type via implicit casts. - Sandbox-defined Groovy classes that shadow specific non-sandbox-defined classes can be used to construct any subclassable type. These vulnerabilities allow 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.
