Summary

High severity vulnerability that affects org.apache.cxf.fediz:fediz-jetty8, org.apache.cxf.fediz:fediz-jetty9, org.apache.cxf.fediz:fediz-spring, org.apache.cxf.fediz:fediz-spring2, and org.apache.cxf.fediz:fediz-spring3

Versions of Apache CXF Fediz prior to 1.4.4 do not fully disable Document Type Declarations (DTDs) when either parsing the Identity Provider response in the application plugins, or in the Identity Provider itself when parsing certain XML-based parameters.

Impact

The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.

Affected versions

org.apache.cxf.fediz:fediz-spring (< 1.4.4) org.apache.cxf.fediz:fediz-spring2 (< 1.4.4) org.apache.cxf.fediz:fediz-spring3 (< 1.4.4) org.apache.cxf.fediz:fediz-jetty8 (< 1.4.4) org.apache.cxf.fediz:fediz-jetty9 (< 1.4.4)

Security releases

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

  1. What is CVE-2018-8038? CVE-2018-8038 is a high-severity improper input validation vulnerability in org.apache.cxf.fediz:fediz-spring (maven), affecting versions < 1.4.4. It is fixed in 1.4.4. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
  2. Which packages are affected by CVE-2018-8038?
    • org.apache.cxf.fediz:fediz-spring (maven) (versions < 1.4.4)
    • org.apache.cxf.fediz:fediz-spring2 (maven) (versions < 1.4.4)
    • org.apache.cxf.fediz:fediz-spring3 (maven) (versions < 1.4.4)
    • org.apache.cxf.fediz:fediz-jetty8 (maven) (versions < 1.4.4)
    • org.apache.cxf.fediz:fediz-jetty9 (maven) (versions < 1.4.4)
  3. Is there a fix for CVE-2018-8038? Yes. CVE-2018-8038 is fixed in 1.4.4. Upgrade to this version or later.
  4. Is CVE-2018-8038 exploitable, and should I be worried? Whether CVE-2018-8038 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.

  5. What actually determines whether CVE-2018-8038 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.
  6. How do I fix CVE-2018-8038?
    • Upgrade org.apache.cxf.fediz:fediz-spring to 1.4.4 or later
    • Upgrade org.apache.cxf.fediz:fediz-spring2 to 1.4.4 or later
    • Upgrade org.apache.cxf.fediz:fediz-spring3 to 1.4.4 or later
