How to Fix CVE-2017-7656

To remediate this vulnerability, upgrade all affected Jetty server 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.eclipse.jetty:jetty-server fixed: 9.3.24.v20180605 
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-server</artifactId>
    <version>9.3.24.v20180605</version>
</dependency>
org.eclipse.jetty:jetty-server fixed: 9.4.11.v20180605 
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-server</artifactId>
    <version>9.4.11.v20180605</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.eclipse.jetty

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2017-7656, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.eclipse.jetty

Analyze the terminal output to locate any version of Jetty server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.3.24.v20180605), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.eclipse.jetty 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-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling'), where the product acts as an intermediary http agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed http requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination. In Jetty server, 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

Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), contain an HTTP Request Smuggling Vulnerability that can result in cache poisoning.
