This flaw allows an attacker with access to the Ceph cluster network to authenticate with the Ceph service via a packet sniffer and perform actions allowed by the Ceph service. This issue is a reintroduction of CVE-2018-1128, affecting the msgr2 protocol. The msgr 2 protocol is used for all communication except older clients that do not support the msgr2 protocol. The msgr1 protocol is not affected. The highest threat from this vulnerability is to confidentiality, integrity, and system availability."},{"lang":"es","value":"Se encontró un fallo en el protocolo de autenticación Cephx en versiones anteriores a 15.2.6 y anteriores a 14.2.14, donde no verifica los clientes de Ceph correctamente y luego es vulnerable a ataques de repetición en Nautilus. Este fallo permite a un atacante con acceso a la red del clúster Ceph autenticarse con el servicio Ceph por medio de un rastreador de paquetes y llevar a cabo acciones permitidas por el servicio Ceph. Este problema es una reintroducción del CVE-2018-1128, que afecta al protocolo msgr2. El protocolo msgr 2 se utiliza para todas las comunicaciones excepto los clientes más antiguos que no son compatibles con el protocolo msgr2. El protocolo msgr1 no está afectado. La mayor amenaza de esta vulnerabilidad es la confidencialidad, integridad y disponibilidad del sistema"}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:A/AC:L/Au:N/C:P/I:P/A:P","baseScore":5.8,"accessVector":"ADJACENT_NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":6.5,"impactScore":6.4,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"secalert@redhat.com","type":"Secondary","description":[{"lang":"en","value":"CWE-294"}]},{"source":"nvd@nist.gov","type":"Secondary","description":[{"lang":"en","value":"CWE-294"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:ceph:*:*:*:*:*:*:*:*","versionEndExcluding":"14.2.14","matchCriteriaId":"A26D687E-2AC6-45AB-8E53-4ED8624E171B"},{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:ceph:*:*:*:*:*:*:*:*","versionStartIncluding":"15.0.0","versionEndExcluding":"15.2.6","matchCriteriaId":"624E6A97-9AC6-4A37-8F4F-0DBB0D7F1D87"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:ceph_storage:2.0:*:*:*:*:*:*:*","matchCriteriaId":"D07DF15E-FE6B-4DAF-99BB-2147CF7D7EEA"},{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:ceph_storage:4.0:*:*:*:*:*:*:*","matchCriteriaId":"D6E54096-5D45-4CB2-AC9A-DDB55BF2B94C"},{"vulnerable":true,"criteria":"cpe:2.3:a:redhat:openshift_container_platform:4.0:*:*:*:*:*:*:*","matchCriteriaId":"932D137F-528B-4526-9A89-CD59FA1AB0FE"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:fedoraproject:fedora:33:*:*:*:*:*:*:*","matchCriteriaId":"E460AA51-FCDA-46B9-AE97-E6676AA5E194"}]}]}],"references":[{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1890354","source":"secalert@redhat.com","tags":["Issue Tracking","Third Party Advisory"]},{"url":"https://ceph.io/community/v15-2-6-octopus-released/","source":"secalert@redhat.com","tags":["Release Notes","Vendor Advisory"]},{"url":"https://ceph.io/releases/v14-2-14-nautilus-released/","source":"secalert@redhat.com","tags":["Release Notes","Vendor Advisory"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UBC4KZ44QUQENTYZPVHORGL4K2KV5V4F/","source":"secalert@redhat.com"},{"url":"https://security.gentoo.org/glsa/202105-39","source":"secalert@redhat.com","tags":["Third Party Advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1890354","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking","Third Party Advisory"]},{"url":"https://ceph.io/community/v15-2-6-octopus-released/","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes","Vendor Advisory"]},{"url":"https://ceph.io/releases/v14-2-14-nautilus-released/","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes","Vendor Advisory"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UBC4KZ44QUQENTYZPVHORGL4K2KV5V4F/","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://security.gentoo.org/glsa/202105-39","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory"]}]}}]}
