No CVSS score has been assigned to CVE-2013-2067 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2013-2067?

CVE-2013-2067 affects the following packages: org.apache.tomcat:tomcat (Maven), org.apache.tomcat:tomcat (Maven). Ecosystems affected: Maven.

How do I fix CVE-2013-2067?

Update org.apache.tomcat:tomcat to 6.0.37 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-2067 is resolved across your whole dependency graph.

How do I detect CVE-2013-2067 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-2013-2067 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-2013-2067?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2013-2067 can be triaged on real exposure rather than presence alone.

Is CVE-2013-2067 actively exploited in the wild?

No public exploit code has been indexed for CVE-2013-2067 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2013-2067?

CVE-2013-2067 has an EPSS (Exploit Prediction Scoring System) score of 7.1%, 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-2013-2067?

CVE-2013-2067 is classified as Improper Authentication (CWE-287). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2013-2067 published, and has it been updated?

CVE-2013-2067 was published on May 14, 2022 and was last updated on November 8, 2023. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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/authenticator/FormAuthenticator.java in the form authentication feature in Apache Tomcat 6.0.21 through 6.0.36 and 7.x before 7.0.33 does not properly handle the relationships between authentication requirements and sessions, which allows remote attackers to inject a request into a session by sending this request during completion of the login form, a variant of a session fixation attack.

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.

Red HatModerate

This flaw allows an attacker to circumvent a session fixation prevention mechanism which was implemented in tomcat 5.5.x >= 5.5.29, 6.0.x >= 6.0.21 and 7.x. Earlier versions of tomcat do not include this mechanism, and are therefore not affected by this flaw. JBoss Web as included in JBoss 5.x products also does not…
