How to Fix CVE-2017-3156

To remediate this vulnerability, upgrade all affected Apache cxf 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.apache.cxf.karaf:apache-cxf fixed: 3.0.13 
<dependency>
    <groupId>org.apache.cxf.karaf</groupId>
    <artifactId>apache-cxf</artifactId>
    <version>3.0.13</version>
</dependency>
org.apache.cxf.karaf:apache-cxf fixed: 3.1.10 
<dependency>
    <groupId>org.apache.cxf.karaf</groupId>
    <artifactId>apache-cxf</artifactId>
    <version>3.1.10</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.apache.cxf.karaf

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2017-3156, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.cxf.karaf

Analyze the terminal output to locate any version of Apache cxf in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.13), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.cxf.karaf 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-385: Covert Timing Channel, where covert timing channels convey information by modulating some aspect of system behavior over time, so that the program receiving the information can observe system behavior and infer protected information. In Apache cxf, 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 OAuth2 Hawk and JOSE MAC Validation code in Apache CXF prior to 3.0.13 and 3.1.x prior to 3.1.10 is not using a constant time MAC signature comparison algorithm which may be exploited by sophisticated timing attacks.
