How to Fix CVE-2021-21617

To remediate this vulnerability, upgrade all affected Configurationslicing 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:configurationslicing fixed: 1.52 
<dependency>
    <groupId>org.jenkins-ci.plugins</groupId>
    <artifactId>configurationslicing</artifactId>
    <version>1.52</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-2021-21617, 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 Configurationslicing in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.52), 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Configurationslicing, 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 Configuration Slicing Plugin 1.51 and earlier does not require POST requests for the form submission endpoint reconfiguring slices, resulting in a cross-site request forgery (CSRF) vulnerability. This vulnerability allows attackers to apply different slice configurations to attacker-specified jobs. Jenkins Configuration Slicing Plugin 1.52 requires POST requests for the affected HTTP endpoint.
