An attacker could exploit this vulnerability by connecting to an AP on an affected device as a wireless client and sending a high rate of traffic over an extended period of time. A successful exploit could allow the attacker to cause the Datagram TLS (DTLS) session to tear down and reset, causing a denial of service (DoS) condition."},{"lang":"es","value":"Una vulnerabilidad en el componente de red del software del punto de acceso (AP) de Cisco podría permitir que un atacante remoto no autenticado cause una interrupción temporal del servicio. Esta vulnerabilidad se debe al uso excesivo de los recursos AP. Un atacante podría aprovechar esta vulnerabilidad conectándose a un AP en un dispositivo afectado como cliente inalámbrico y enviando una alta tasa de tráfico durante un período prolongado de tiempo. Un exploit exitoso podría permitir al atacante provocar que la sesión de Datagram TLS (DTLS) se interrumpa y se reinicie, provocando una condición de denegación de servicio (DoS)."}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","baseScore":5.8,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":3.9,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","baseScore":8.6,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":4.0}]},"weaknesses":[{"source":"psirt@cisco.com","type":"Secondary","description":[{"lang":"en","value":"CWE-400"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-400"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:catalyst_9166_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"17.6.6","matchCriteriaId":"C9E58B3F-A839-40D2-94E8-DBBA4233CB6A"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9166:-:*:*:*:*:*:*:*","matchCriteriaId":"774AEB3E-5D6A-4E66-B0B4-C014A7C180E6"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:catalyst_9164_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"17.6.6","matchCriteriaId":"674A6482-211F-43C7-BB67-4B0DBEB08E2F"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9164:-:*:*:*:*:*:*:*","matchCriteriaId":"96E81F0A-5B5C-4DD3-A56F-C7BF53D4B070"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:catalyst_9136_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"17.6.6","matchCriteriaId":"02DBA4EC-6404-467A-A862-5CF3704CA8CF"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9136:-:*:*:*:*:*:*:*","matchCriteriaId":"09185C81-6FDF-4E6D-B8F7-E4B5D77909F4"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:catalyst_9130_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"17.6.6","matchCriteriaId":"396ED75A-FF33-4AE5-BE9F-DBFD111532CF"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9130:-:*:*:*:*:*:*:*","matchCriteriaId":"E1C8E35A-5A9B-4D56-A753-937D5CFB5B19"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:catalyst_9124_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"17.6.6","matchCriteriaId":"51EEDFEA-1E40-471B-8B2E-363C248F816E"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9124:-:*:*:*:*:*:*:*","matchCriteriaId":"C11EF240-7599-4138-B7A7-17E4479F5B83"}]}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-click-ap-dos-wdcXkvnQ","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-click-ap-dos-wdcXkvnQ","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
