How to Fix CVE-2024-6762

To remediate this vulnerability, upgrade all affected Jetty servlets 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-servlets fixed: 10.0.18 
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-servlets</artifactId>
    <version>10.0.18</version>
</dependency>
org.eclipse.jetty:jetty-servlets fixed: 11.0.18 
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-servlets</artifactId>
    <version>11.0.18</version>
</dependency>
org.eclipse.jetty:jetty-servlets fixed: 12.0.4 
<dependency>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-servlets</artifactId>
    <version>12.0.4</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-2024-6762, 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 servlets in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 10.0.18), 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. In Jetty servlets, 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

### Impact Jetty PushSessionCacheFilter can be exploited by unauthenticated users to launch remote DoS attacks by exhausting the server’s memory. ### Patches * https://github.com/jetty/jetty.project/pull/9715 * https://github.com/jetty/jetty.project/pull/9716 ### Workarounds The session usage is intrinsic to the design of the PushCacheFilter. The issue can be avoided by: + not using the PushCacheFilter. Push has been deprecated by the various IETF specs and early hints responses should be used instead. + reducing the reducing the idle timeout on unauthenticated sessions will reduce the time such session stay in memory. + configuring a session cache to use [session passivation](https://jetty.org/docs/jetty/12/programming-guide/server/session.html), so that sessions are not stored in memory, but rather in a database or file system that may have significantly more capacity than memory. ### References * https://github.com/jetty/jetty.project/pull/10756 * https://github.com/jetty/jetty.project/pull/10755
