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. 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-2014-0056 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 pinpoints whether CVE-2014-0056 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-2014-0056 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.

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.
