How severe is CVE-2013-2071?

No CVSS score has been assigned to CVE-2013-2071 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2013-2071?

CVE-2013-2071 affects the following packages: org.apache.tomcat:tomcat (Maven). Ecosystems affected: Maven.

How do I fix CVE-2013-2071?

Update org.apache.tomcat:tomcat to 7.0.40 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-2071 is resolved across your whole dependency graph.

How do I detect CVE-2013-2071 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.tomcat:tomcat, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2013-2071 if there is no patch (or I can't update yet)?

Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.

Is CVE-2013-2071 actively exploited in the wild?

Yes. There are 1 known exploit references for CVE-2013-2071, including 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-2013-2071?

CVE-2013-2071 has an EPSS (Exploit Prediction Scoring System) score of 6.5%, placing it in the 94th 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. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2013-2071?

CVE-2013-2071 is classified as Information Exposure (CWE-200). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2013-2071 published, and has it been updated?

CVE-2013-2071 was published on May 17, 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.

☕org.apache.tomcat:tomcat

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

java/org/apache/catalina/core/AsyncContextImpl.java in Apache Tomcat 7.x before 7.0.40 does not properly handle the throwing of a RuntimeException in an AsyncListener in an application, which allows context-dependent attackers to obtain sensitive request information intended for other applications in opportunistic circumstances via an application that records the requests that it processes.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
