How to Fix CVE-2018-1000600

To remediate this vulnerability, upgrade all affected Github 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.coravy.hudson.plugins.github:github fixed: 1.29.2 
<dependency>
    <groupId>com.coravy.hudson.plugins.github</groupId>
    <artifactId>github</artifactId>
    <version>1.29.2</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.coravy.hudson.plugins.github

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2018-1000600, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=com.coravy.hudson.plugins.github

Analyze the terminal output to locate any version of Github in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.29.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=com.coravy.hudson.plugins.github 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 Github, 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 GitHub Plugin 1.29.1 and earlier in GitHubTokenCredentialsCreator.java that allows attackers to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.
