How to Fix CVE-2020-10740

To remediate this vulnerability, upgrade all affected Wildfly parent 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.wildfly:wildfly-parent fixed: 20.0.0.Final 
<dependency>
    <groupId>org.wildfly</groupId>
    <artifactId>wildfly-parent</artifactId>
    <version>20.0.0.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.wildfly

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2020-10740, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.wildfly

Analyze the terminal output to locate any version of Wildfly parent in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 20.0.0.Final), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.wildfly 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-502: Deserialization of Untrusted Data, where the product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid. In Wildfly parent, 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 vulnerability was found in Wildfly in versions before 20.0.0.Final, where a remote deserialization attack is possible in the Enterprise Application Beans(EJB) due to lack of validation/filtering capabilities in wildfly.
