How to Fix CVE-2021-3396

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: 27.0.4

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-2021-3396, 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 27.0.4), 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-863: Incorrect Authorization, where the product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. 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

OpenNMS Meridian 2016, 2017, 2018 before 2018.1.25, 2019 before 2019.1.16, and 2020 before 2020.1.5, Horizon 1.2 through 27.0.4, and Newts <1.5.3 has Incorrect Access Control, which allows local and remote code execution using JEXL expressions.
