How to Fix CVE-2023-46655

To remediate this vulnerability, upgrade all affected Electricflow 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:electricflow fixed: 1.1.33 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>electricflow</artifactId>
    <version>1.1.33</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-2023-46655, 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 Electricflow in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.33), 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-59: Improper Link Resolution Before File Access ('Link Following'), where the product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. In Electricflow, 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 CloudBees CD Plugin temporarily copies files from an agent workspace to the controller in preparation for publishing them in the 'CloudBees CD - Publish Artifact' post-build step. CloudBees CD Plugin 1.1.32 and earlier follows symbolic links to locations outside of the temporary directory on the controller when collecting the list of files to publish. This allows attackers able to configure jobs to publish arbitrary files from the Jenkins controller file system to the previously configured CloudBees CD server. CloudBees CD Plugin 1.1.33 ensures that only files located within the expected directory are published.
