How to Fix CVE-2021-25930

To remediate this vulnerability, upgrade all affected Opennms 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.opennms:opennms fixed: 27.1.1 
<dependency>
    <groupId>org.opennms</groupId>
    <artifactId>opennms</artifactId>
    <version>27.1.1</version>
</dependency>
org.opennms:opennms-config fixed: 27.1.1 
<dependency>
    <groupId>org.opennms</groupId>
    <artifactId>opennms-config</artifactId>
    <version>27.1.1</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.opennms

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-25930, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.opennms

Analyze the terminal output to locate any version of Opennms in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 27.1.1), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.opennms 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-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Opennms, 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 OpenNMS Horizon, versions opennms-1-0-stable through opennms-27.1.1; OpenNMS Meridian, versions meridian-foundation-2015.1.0-1 through meridian-foundation-2019.1.18-1; meridian-foundation-2020.1.0-1 through meridian-foundation-2020.1.6-1 are vulnerable to CSRF, due to no CSRF protection, and since there is no validation of an existing user name while renaming a user. As a result, privileges of the renamed user are being overwritten by the old user and the old user is being deleted from the user list.
