How to Fix CVE-2019-1003024

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: 1.53 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>script-security</artifactId>
    <version>1.53</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-2019-1003024, 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 1.53), 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 General Security Weakness. 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

The previously implemented script security sandbox protections prohibiting the use of unsafe AST transforming annotations such as `@Grab` ([2019-01-08 fix for SECURITY-1266](https://www.jenkins.io/security/advisory/2019-01-08/#SECURITY-1266)) could be circumvented through use of various Groovy language features: - Use of `AnnotationCollector` - Import aliasing - Referencing annotation types using their full class name This allowed users with Overall/Read permission, or the ability to control Jenkinsfile or sandboxed Pipeline shared library contents in SCM, to bypass the sandbox protection and execute arbitrary code on the Jenkins controller. Using `AnnotationCollector` is now newly prohibited in sandboxed scripts such as Pipelines. Importing any of the annotations considered unsafe will now result in an error. During the compilation phase, both simple and full class names of prohibited annotations are rejected for element annotations.
