How to Fix CVE-2023-0870

To remediate this vulnerability, upgrade all affected Opennms webapp 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-webapp fixed: 31.0.6 
<dependency>
    <groupId>org.opennms</groupId>
    <artifactId>opennms-webapp</artifactId>
    <version>31.0.6</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-2023-0870, 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 webapp in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 31.0.6), 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 webapp, 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 form can be manipulated with cross-site request forgery in multiple versions of OpenNMS Meridian and Horizon. This can potentially allow an attacker to gain access to confidential information and compromise integrity. The solution is to upgrade to Meridian 2023.1.1 or Horizon 31.0.6 or newer. Meridian and Horizon installation instructions state that they are intended for installation within an organization's private networks and should not be directly accessible from the Internet.
