How severe is CVE-2014-0056?

No CVSS score has been assigned to CVE-2014-0056 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2014-0056?

CVE-2014-0056 affects the following packages: neutron (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2014-0056?

Update neutron to 2013.2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-0056 is resolved across your whole dependency graph.

How do I detect CVE-2014-0056 in my PyPI dependencies?

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

How do I mitigate CVE-2014-0056 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-2014-0056?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2014-0056 can be triaged on real exposure rather than presence alone.

Is CVE-2014-0056 actively exploited in the wild?

No public exploit code has been indexed for CVE-2014-0056 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-2014-0056?

CVE-2014-0056 has an EPSS (Exploit Prediction Scoring System) score of 1.4%, placing it in the 72th 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.

When was CVE-2014-0056 published, and has it been updated?

CVE-2014-0056 was published on May 8, 2014 and was last updated on July 7, 2026. 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 PyPI packages — download data is not available via public APIs for these ecosystems.

Description

The l3-agent in OpenStack Neutron 2012.2 before 2013.2.3 does not check the tenant id when creating ports, which allows remote authenticated users to plug ports into the routers of arbitrary tenants via the device id in a port-create command.

Detection & mitigation playbook

Open-source dependency

Detect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for neutron, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update neutron to 2013.2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-0056 is resolved across your whole dependency graph.
Workarounds
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.
