CVE-2024-8184

Description

There exists a security vulnerability in Jetty's ThreadLimitHandler.getRemote() which
can be exploited by unauthorized users to cause remote denial-of-service (DoS) attack. By
repeatedly sending crafted requests, attackers can trigger OutofMemory errors and exhaust the
server's memory.

Affected Versions

• Jetty 12.0.0-12.0.8 (Supported)
• Jetty 11.0.0-11.0.23 (EOL)
• Jetty 10.0.0-10.0.23 (EOL)
• Jetty 9.3.12-9.4.55 (EOL)

Patched Versions

• Jetty 12.0.9
• Jetty 11.0.24
• Jetty 10.0.24
• Jetty 9.4.56

Workarounds

Do not use ThreadLimitHandler.
Consider use of QoSHandler instead to artificially limit resource utilization.

Remote DOS attack can cause out of memory

Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service. Typical impact: denial of service.

CVE-2024-8184 has a CVSS score of 5.9 (Medium). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (12.0.9, 10.0.24, 11.0.24, 9.4.56); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2024-8184? CVE-2024-8184 is a medium-severity uncontrolled resource consumption vulnerability in org.eclipse.jetty:jetty-server (maven), affecting versions >= 12.0.0, <= 12.0.8. It is fixed in 12.0.9, 10.0.24, 11.0.24, 9.4.56. Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service.
2. How severe is CVE-2024-8184? CVE-2024-8184 has a CVSS score of 5.9 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of org.eclipse.jetty:jetty-server are affected by CVE-2024-8184? org.eclipse.jetty:jetty-server (maven) versions >= 12.0.0, <= 12.0.8 is affected.
4. Is there a fix for CVE-2024-8184? Yes. CVE-2024-8184 is fixed in 12.0.9, 10.0.24, 11.0.24, 9.4.56. Upgrade to this version or later.
5. Is CVE-2024-8184 exploitable, and should I be worried? Whether CVE-2024-8184 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-8184 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-8184?
   • Upgrade org.eclipse.jetty:jetty-server to 12.0.9 or later
   • Upgrade org.eclipse.jetty:jetty-server to 10.0.24 or later
   • Upgrade org.eclipse.jetty:jetty-server to 11.0.24 or later
   • Upgrade org.eclipse.jetty:jetty-server to 9.4.56 or later
