OpenStack Security Advisory: 2014-008
CVE: CVE-2014-0056
Date: March 27, 2014
Title: Routers can be cross plugged by other tenants
Reporter: Aaron Rosen (VMWare)
Products: Neutron
Affects: 2012.2 versions up to 2013.2.2

Aaron Rosen from VMWare reported a vulnerability where Neutron fails to
perform proper authorization checks when creating ports. By choosing a
device id of a router from a different tenant when creating a port, an
authenticated user can access the network of other tenants. This affects
deployments of Neutron using plugins relying on the l3-agent.

Icehouse (development branch) fix:

Havana fix:

One should perform and audit of the ports that are already attached to
routers after applying this patch and remove ports that a tenant may
have cross plugged.


@maintainer(s): since the package has never been marked as stable, we don't need to stabilize it. After the bump, please remove the affected versions from the tree.

CVE-2014-0056 (
  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.
