How to Fix CVE-2023-6236

To remediate this vulnerability, upgrade all affected WildFly Elytron 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.security:wildfly-elytron-http-oidc fixed: 2.2.5.Final 
<dependency>
    <groupId>org.wildfly.security</groupId>
    <artifactId>wildfly-elytron-http-oidc</artifactId>
    <version>2.2.5.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.security

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2023-6236, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.wildfly.security

Analyze the terminal output to locate any version of WildFly Elytron in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.5.Final), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.wildfly.security 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-345: Insufficient Verification of Data Authenticity, where the product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data. In WildFly Elytron, 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 found in JBoss EAP. When an OIDC app that serves multiple tenants attempts to access the second tenant, it should prompt the user to log in again since the second tenant is secured with a different OIDC configuration. The underlying issue is in OidcSessionTokenStore when determining if a cached token should be used or not. This logic needs to be updated to take into account the new "provider-url" option in addition to the "realm" option.
