How to Fix CVE-2020-14297

To remediate this vulnerability, upgrade all affected Jboss ejb client 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.jboss:jboss-ejb-client fixed: 4.0.34.Final 
<dependency>
    <groupId>org.jboss</groupId>
    <artifactId>jboss-ejb-client</artifactId>
    <version>4.0.34.Final</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.jboss

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-14297, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.jboss

Analyze the terminal output to locate any version of Jboss ejb client in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.34.Final), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.jboss 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Jboss ejb client, 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 flaw was discovered in Wildfly's EJB Client as shipped with Red Hat JBoss EAP 7, where some specific EJB transaction objects may get accumulated over the time and can cause services to slow down and eventually unavailable. An attacker can take advantage and cause denial of service attack and make services unavailable.
