The vulnerability is due to a logic error in the affected software. An attacker could exploit this vulnerability by connecting to and passing traffic through a Layer 3 interface of an affected device, if the interface is configured for MACsec MKA using EAP-TLS and is running in access-session closed mode. A successful exploit could allow the attacker to bypass 802.1x network access controls and gain access to the network."},{"lang":"es","value":"Una vulnerabilidad en la funcionalidad MACsec Key Agreement (MKA) empleando Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) de Cisco IOS XE Software podría permitir que un atacante adyacente sin autenticar omita la autenticación y pase tráfico a través de una interfaz Layer 3 de un dispositivo afectado. La vulnerabilidad se debe a un error de lógica en el software afectado. Un atacante podría explotar esta vulnerabilidad conectándose y pasando tráfico mediante una interfaz Layer 3 de un dispositivo afectado, si dicha interfaz está configurada para MKA MACsec utilizando EAP-TLS y se está ejecutando en modo \"access-session closed\". Su explotación con éxito podría permitir que el atacante omita los controles de acceso de red 802.1x y obtenga acceso a la red."}],"metrics":{"cvssMetricV30":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","baseScore":8.1,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":2.8,"impactScore":5.2}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:A/AC:L/Au:N/C:P/I:P/A:N","baseScore":4.8,"accessVector":"ADJACENT_NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"NONE"},"baseSeverity":"MEDIUM","exploitabilityScore":6.5,"impactScore":4.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-284"}]},{"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:o:cisco:ios_xe:16.8.1:*:*:*:*:*:*:*","matchCriteriaId":"57D4F634-03D5-4D9F-901C-7E9CE45F2F38"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ios_xe:16.9.1:*:*:*:*:*:*:*","matchCriteriaId":"119A964D-ABC8-424D-8097-85B832A833BD"}]}]}],"references":[{"url":"http://www.securityfocus.com/bid/105416","source":"psirt@cisco.com","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-macsec","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/105416","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180926-macsec","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
