How to Fix CVE-2020-27219

To remediate this vulnerability, upgrade all affected Hawkbit parent 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.eclipse.hawkbit:hawkbit-parent fixed: 0.3.0M7 
<dependency>
    <groupId>org.eclipse.hawkbit</groupId>
    <artifactId>hawkbit-parent</artifactId>
    <version>0.3.0M7</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.eclipse.hawkbit

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-27219, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.eclipse.hawkbit

Analyze the terminal output to locate any version of Hawkbit parent in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3.0M7), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.eclipse.hawkbit 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 Hawkbit parent, 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

In all version of Eclipse Hawkbit prior to 0.3.0M7, the HTTP 404 (Not Found) JSON response body returned by the REST API may contain unsafe characters within the path attribute. Sending a POST request to a non existing resource will return the full path from the given URL unescaped to the client.
