How to Fix CVE-2020-1954

To remediate this vulnerability, upgrade all affected Cxf rt management 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.apache.cxf:cxf-rt-management fixed: 3.2.13 
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-management</artifactId>
    <version>3.2.13</version>
</dependency>
org.apache.cxf:cxf-rt-management fixed: 3.3.6 
<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-management</artifactId>
    <version>3.3.6</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.apache.cxf

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-1954, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.cxf

Analyze the terminal output to locate any version of Cxf rt management in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.2.13), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.cxf 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Cxf rt management, 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

Apache CXF has the ability to integrate with JMX by registering an `InstrumentationManager` extension with the CXF bus. If the `createMBServerConnectorFactory` property of the default `InstrumentationManagerImpl` is not disabled, then it is vulnerable to a man-in-the-middle (MITM) style attack. An attacker on the same host can connect to the registry and rebind the entry to another server, thus acting as a proxy to the original. They are then able to gain access to all of the information that is sent and received over JMX.
