How to Fix CVE-2022-43403

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: 1184.v85d16b_d851b_3 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>script-security</artifactId>
    <version>1184.v85d16b_d851b_3</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-2022-43403, 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 1184.v85d16b_d851b_3), 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 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

A sandbox bypass vulnerability involving casting an array-like value to an array type in Jenkins Script Security Plugin 1183.v774b_0b_0a_a_451 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. Script Security Plugin 1184.v85d16b_d851b_3 intercepts per-element casts when casting array-like values to array types.
