The vulnerability is due to incorrect packet processing during the WPA2 and WPA3 authentication handshake when configured for dot1x or pre-shared key (PSK) authentication key management (AKM) with 802.11r BSS Fast Transition (FT) enabled. An attacker could exploit this vulnerability by sending a crafted authentication packet to an affected device. A successful exploit could cause an affected device to reload, resulting in a DoS condition."},{"lang":"es","value":"Una vulnerabilidad en la implementación de seguridad WPA2 y WPA3 de Cisco IOS XE Wireless Controller Software para Cisco Catalyst 9000 Family, podría permitir a un atacante adyacente no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad es debido al procesamiento incorrecto de paquetes durante el protocolo de enlace de autenticación WPA2 y WPA3 cuando se configura para la administración de claves de autenticación (AKM) dot1x o de clave precompartida (PSK) con 802.11r BSS Fast Transition (FT) habilitado. Un atacante podría explotar esta vulnerabilidad mediante el envío de un paquete de autenticación diseñado hacia un dispositivo afectado. Una explotación con éxito podría hacer que un dispositivo afectado se recargue, resultando en una condición DoS."}],"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:N/I:N/A:H","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":3.6}],"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","baseScore":7.4,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":4.0}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:A/AC:M/Au:N/C:N/I:N/A:C","baseScore":5.7,"accessVector":"ADJACENT_NETWORK","accessComplexity":"MEDIUM","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"COMPLETE"},"baseSeverity":"MEDIUM","exploitabilityScore":5.5,"impactScore":6.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-20"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:ios_xe:16.12.1s:*:*:*:*:*:*:*","matchCriteriaId":"9027A528-2588-4C06-810B-5BB313FE4323"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9300:-:*:*:*:*:*:*:*","matchCriteriaId":"0972076B-5C87-44B3-90EC-4C200B89318A"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9400:-:*:*:*:*:*:*:*","matchCriteriaId":"737F22AB-C5A9-4A18-BA3D-38A222491397"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9500:-:*:*:*:*:*:*:*","matchCriteriaId":"176ACF88-6112-4179-8492-50C50577B300"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9800-40:-:*:*:*:*:*:*:*","matchCriteriaId":"1B9ED0E5-CB20-4106-9CF2-8EB587B33543"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9800-80:-:*:*:*:*:*:*:*","matchCriteriaId":"2B0E620C-8E09-4F7C-A326-26013173B993"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9800-cl:-:*:*:*:*:*:*:*","matchCriteriaId":"FF93F1C8-669F-4ECB-8D81-ECDA7B550175"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9800-l:-:*:*:*:*:*:*:*","matchCriteriaId":"2E0BA345-B7D7-4975-9199-4DC7875BBFD0"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wpa-dos-cXshjerc","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wpa-dos-cXshjerc","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
