How severe is CVE-2013-2134?

No CVSS score has been assigned to CVE-2013-2134 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2013-2134?

CVE-2013-2134 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-2013-2134?

Update org.apache.struts:struts2-core to 2.3.14.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-2134 is resolved across your whole dependency graph.

How do I detect CVE-2013-2134 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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2013-2134 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-2013-2134?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2013-2134 can be triaged on real exposure rather than presence alone.

Is CVE-2013-2134 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2013-2134, including 1 documented proof-of-concept exploit on Exploit-DB. 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-2013-2134?

CVE-2013-2134 has an EPSS (Exploit Prediction Scoring System) score of 70.2%, placing it in the 99th 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.

What type of vulnerability is CVE-2013-2134?

CVE-2013-2134 is classified as Code Injection (CWE-94). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2013-2134 published, and has it been updated?

CVE-2013-2134 was published on May 14, 2022 and was last updated on December 5, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
