How to Fix CVE-2017-14387

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

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

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2017-14387, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

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

Note: The mvn dependency:tree 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 General Security Weakness. In Software, 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

The NFS service in EMC Isilon OneFS 8.1.0.0, 8.0.1.0 - 8.0.1.1, and 8.0.0.0 - 8.0.0.4 maintains default NFS export settings (including the NFS export security flavor for authentication) that can be leveraged by current and future NFS exports. This NFS service contained a flaw that did not properly propagate changes made to the default security flavor to all new and existing NFS exports that are configured to use default NFS export settings and that are mounted after those changes are made. This flaw may potentially allow NFS clients to access affected NFS exports using the default and potentially weaker security flavor even if a more secure one was selected to be used by the OneFS administrator, aka an "NFS Export Security Setting Fallback Vulnerability."
