{"id":"GHSA-x634-34m9-96mp","summary":"OpensStack Neutron Denial of Service Vulnerability","details":"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.","aliases":["CVE-2018-14635","PYSEC-2018-93"],"modified":"2024-09-25T21:00:51.908005Z","published":"2022-05-13T01:07:33Z","database_specific":{"nvd_published_at":"2018-09-10T19:29:00Z","cwe_ids":["CWE-20"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-04-08T18:53:04Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-14635"},{"type":"WEB","url":"https://github.com/openstack/neutron/commit/54aa6e81cb17b33ce4d5d469cc11dec2869c762d"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2018:2710"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2018:2715"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2018:2721"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2018:3792"},{"type":"WEB","url":"https://bugs.launchpad.net/neutron/+bug/1757482"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14635"},{"type":"WEB","url":"https://git.openstack.org/cgit/openstack/neutron/commit/?id=54aa6e81cb17b33ce4d5d469cc11dec2869c762d"},{"type":"PACKAGE","url":"https://github.com/openstack/neutron"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/neutron/PYSEC-2018-93.yaml"}],"affected":[{"package":{"name":"neutron","ecosystem":"PyPI","purl":"pkg:pypi/neutron"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0.0.0b1"},{"fixed":"13.0.0.0b2"}]}],"versions":["13.0.0.0b1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-x634-34m9-96mp/GHSA-x634-34m9-96mp.json"}},{"package":{"name":"neutron","ecosystem":"PyPI","purl":"pkg:pypi/neutron"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"11.0.6"}]}],"versions":["0.0","10.0.5","10.0.6","10.0.7","11.0.3","11.0.4","11.0.5"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-x634-34m9-96mp/GHSA-x634-34m9-96mp.json"}},{"package":{"name":"neutron","ecosystem":"PyPI","purl":"pkg:pypi/neutron"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"12.0.0"},{"fixed":"12.0.4"}]}],"versions":["12.0.0","12.0.1","12.0.2","12.0.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-x634-34m9-96mp/GHSA-x634-34m9-96mp.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
