How to Fix CVE-2019-6804

To remediate this vulnerability, upgrade all affected Rundeck 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.rundeck:rundeck fixed: 3.0.13 
<dependency>
    <groupId>org.rundeck</groupId>
    <artifactId>rundeck</artifactId>
    <version>3.0.13</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.rundeck

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2019-6804, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.rundeck

Analyze the terminal output to locate any version of Rundeck in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.13), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.rundeck 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.
