CVE-2018-14636 (GCVE-0-2018-14636)

Vulnerability from cvelistv5 – Published: 2018-09-10 19:00 – Updated: 2024-08-05 09:38
VLAI?
Summary
Live-migrated instances are briefly able to inspect traffic for other instances on the same hypervisor. This brief window could be extended indefinitely if the instance's port is set administratively down prior to live-migration and kept down after the migration is complete. This is possible due to the Open vSwitch integration bridge being connected to the instance during migration. When connected to the integration bridge, all traffic for instances using the same Open vSwitch instance would potentially be visible to the migrated guest, as the required Open vSwitch VLAN filters are only applied post-migration. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3, 11.0.5 are vulnerable.

Esto es posible debido a que el puente de integraci\u00f3n de Open vSwitch se conecta a la instancia durante la migraci\u00f3n. Al conectarse al puente de integraci\u00f3n, todo el tr\u00e1fico para las instancias que emplean la misma instancia de Open vSwitch ser\u00edan visibles para el invitado migrado, ya que los filtros VLAN de Open vSwitch necesarios solo se aplican tras la migraci\u00f3n. Las versiones de openstack-neutron anteriores a la 13.0.0.0b2, 12.0.3 y 11.0.5 son vulnerables.\"}],\"metrics\":{\"cvssMetricV30\":[{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N\",\"baseScore\":5.3,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":1.6,\"impactScore\":3.6},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.0\",\"vectorString\":\"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N\",\"baseScore\":5.3,\"baseSeverity\":\"MEDIUM\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"NONE\"},\"exploitabilityScore\":1.6,\"impactScore\":3.6}],\"cvssMetricV2\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"2.0\",\"vectorString\":\"AV:N/AC:M/Au:S/C:P/I:N/A:N\",\"baseScore\":3.5,\"accessVector\":\"NETWORK\",\"accessComplexity\":\"MEDIUM\",\"authentication\":\"SINGLE\",\"confidentialityImpact\":\"PARTIAL\",\"integrityImpact\":\"NONE\",\"availabilityImpact\":\"NONE\"},\"baseSeverity\":\"LOW\",\"exploitabilityScore\":6.8,\"impactScore\":2.9,\"acInsufInfo\":false,\"obtainAllPrivilege\":false,\"obtainUserPrivilege\":false,\"obtainOtherPrivilege\":false,\"userInteractionRequired\":false}]},\"weaknesses\":[{\"source\":\"secalert@redhat.com\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-300\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"NVD-CWE-noinfo\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:openstack:neutron:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"7.0.0\",\"versionEndIncluding\":\"11.0.4\",\"matchCriteriaId\":\"F698F960-65DD-4374-ADE9-8971ADB57030\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:openstack:neutron:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"12.0.0\",\"versionEndIncluding\":\"12.0.2\",\"matchCriteriaId\":\"52B626FD-5547-4E6D-B7AD-76B96FDFE56F\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:openstack:neutron:13.0.0:b1:*:*:*:*:*:*\",\"matchCriteriaId\":\"2DC16584-6072-4821-BEA6-4042FEAEB205\"}]}]}],\"references\":[{\"url\":\"https://bugs.launchpad.net/neutron/+bug/1734320\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Issue Tracking\",\"Third Party Advisory\"]},{\"url\":\"https://bugs.launchpad.net/neutron/+bug/1767422\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Issue Tracking\",\"Third Party Advisory\"]},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14636\",\"source\":\"secalert@redhat.com\",\"tags\":[\"Issue Tracking\",\"Third Party Advisory\"]},{\"url\":\"https://bugs.launchpad.net/neutron/+bug/1734320\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Issue Tracking\",\"Third Party Advisory\"]},{\"url\":\"https://bugs.launchpad.net/neutron/+bug/1767422\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Issue Tracking\",\"Third Party Advisory\"]},{\"url\":\"https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14636\",\"source\":\"af854a3a-2127-422b-91ae-364da2661108\",\"tags\":[\"Issue Tracking\",\"Third Party Advisory\"]}]}}"
