CVSS 3.0
6.5 mediumCVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2018-14635
Medium (6.5). EPSS 2.5% chance of exploitation in the next 30 days. Fixed in neutron 11.0.6, 12.0.4, 13.0.0.0b2.
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.
