How to Fix CVE-2016-9589
To remediate this vulnerability, upgrade all affected Wildfly undertow dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.wildfly</groupId>
<artifactId>wildfly-undertow</artifactId>
<version>11.0.0.Beta1</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.wildflyHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2016-9589, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.wildflyAnalyze the terminal output to locate any version of Wildfly undertow in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 11.0.0.Beta1), 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.
