How to Fix CVE-2018-1000196

To remediate this vulnerability, upgrade all affected Gitlab hook 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.ruby-plugins:gitlab-hook fixed: Latest secure release 
<dependency>
    <groupId>org.jenkins-ci.ruby-plugins</groupId>
    <artifactId>gitlab-hook</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=org.jenkins-ci.ruby-plugins

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-1000196, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jenkins-ci.ruby-plugins

Analyze the terminal output to locate any version of Gitlab hook 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=org.jenkins-ci.ruby-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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Gitlab hook, 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 exposure of sensitive information vulnerability exists in Jenkins Gitlab Hook Plugin 1.4.2 and older in gitlab_notifier.rb, views/gitlab_notifier/global.erb that allows attackers with local Jenkins master file system access or control of a Jenkins administrator's web browser (e.g. malicious extension) to retrieve the configured Gitlab token.
