How to Fix CVE-2022-41239

To remediate this vulnerability, upgrade all affected DotCi dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

com.groupon.jenkins-ci.plugins:DotCi fixed: Latest secure release 
<dependency>
    <groupId>com.groupon.jenkins-ci.plugins</groupId>
    <artifactId>DotCi</artifactId>
    <version>Latest secure release</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=com.groupon.jenkins-ci.plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2022-41239, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.groupon.jenkins-ci.plugins

Analyze the terminal output to locate any version of DotCi in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.groupon.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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In DotCi, 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

DotCi Plugin 2.40.00 and earlier does not escape the GitHub user name parameter provided to commit notifications when displaying them in a build cause. This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to submit crafted commit notifications to the `/githook/` endpoint (see also [SECURITY-2867](https://www.jenkins.io/security/advisory/2022-09-21/#SECURITY-2867)). This vulnerability is only exploitable in Jenkins 2.314 and earlier, LTS 2.303.1 and earlier. See the [LTS upgrade guide](https://www.jenkins.io/doc/upgrade-guide/2.303/#SECURITY-2452).
