Summary
Uncontrolled Resource Consumption in Apache CXF
Apache CXF before 2.6.14 and 2.7.x before 2.7.11 allows remote attackers to cause a denial of service (memory consumption) via a large request with the Content-Type set to text/html to a SOAP endpoint, which triggers an error.
Impact
Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service. Typical impact: denial of service.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2014-0109? CVE-2014-0109 is a medium-severity uncontrolled resource consumption vulnerability in org.apache.cxf:cxf-core (maven), affecting versions < 2.6.14. It is fixed in 2.6.14, 2.7.11. Crafted input forces the application to consume excessive CPU, memory, or other resources, degrading or denying service.
- Which versions of org.apache.cxf:cxf-core are affected by CVE-2014-0109? org.apache.cxf:cxf-core (maven) versions < 2.6.14 is affected.
- Is there a fix for CVE-2014-0109? Yes. CVE-2014-0109 is fixed in 2.6.14, 2.7.11. Upgrade to this version or later.
- Is CVE-2014-0109 exploitable, and should I be worried? Whether CVE-2014-0109 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.

- What actually determines whether CVE-2014-0109 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.
