How severe is CVE-2014-0094?

No CVSS score has been assigned to CVE-2014-0094 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2014-0094?

CVE-2014-0094 affects the following packages: org.apache.struts:struts2-core (Maven), org.apache.struts.xwork:xwork-core (Maven). Ecosystems affected: Maven.

How do I fix CVE-2014-0094?

Update org.apache.struts:struts2-core to 2.3.16.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-0094 is resolved across your whole dependency graph.

How do I detect CVE-2014-0094 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.struts:struts2-core. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2014-0094 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2014-0094?

O3 pinpoints whether CVE-2014-0094 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2014-0094 actively exploited in the wild?

Yes. There are 3 known exploit references for CVE-2014-0094, including 2 documented proof-of-concept exploits on Exploit-DB and 1 in-the-wild exploitation observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2014-0094?

CVE-2014-0094 has an EPSS (Exploit Prediction Scoring System) score of 99.5%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

When was CVE-2014-0094 published, and has it been updated?

CVE-2014-0094 was published on May 14, 2022 and was last updated on December 6, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
