CWE-20

Description

When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3 and 11.0.5 are vulnerable.

Affected configurations

• redhat openstack 10 • redhat openstack 12 • redhat openstack 13 • openstack neutron (>= 11.0.0 <= 11.0.5) • openstack neutron (>= 12.0.0 <= 12.0.3) • openstack neutron 13.0.0.0
