An attacker could exploit this vulnerability by sending a series of specific wireless packets to an affected device. A successful exploit could allow the attacker to consume resources on an affected device. A sustained attack could lead to the disruption of the Control and Provisioning of Wireless Access Points (CAPWAP) tunnel and intermittent loss of wireless client traffic."},{"lang":"es","value":"Una vulnerabilidad en la funcionalidad de procesamiento de paquetes del software del punto de acceso (AP) de Cisco podría permitir que un atacante adyacente no autenticado agote los recursos de un dispositivo afectado. Esta vulnerabilidad se debe a una gestión insuficiente de los recursos a la hora de gestionar determinados tipos de tráfico. Un atacante podría aprovechar esta vulnerabilidad enviando una serie de paquetes inalámbricos específicos a un dispositivo afectado. Un exploit exitoso podría permitir al atacante consumir recursos en un dispositivo afectado. Un ataque sostenido podría provocar la interrupción del túnel de control y aprovisionamiento de puntos de acceso inalámbricos (CAPWAP) y la pérdida intermitente de tráfico de clientes inalámbricos."}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","baseScore":4.7,"baseSeverity":"MEDIUM","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":2.8,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L","baseScore":4.7,"baseSeverity":"MEDIUM","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW"},"exploitabilityScore":2.8,"impactScore":1.4}]},"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":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:wireless_lan_controller_software:*:*:*:*:*:*:*:*","versionEndExcluding":"8.10.190.0","matchCriteriaId":"A084C31F-54F0-444E-A2F0-817F1C8B3BFE"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:catalyst_9800_embedded_wireless_controller_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"17.3.8","matchCriteriaId":"649DA1E0-2F09-4855-9715-9574FC28287B"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:catalyst_9800_embedded_wireless_controller_firmware:*:*:*:*:*:*:*:*","versionStartIncluding":"17.4.0","versionEndExcluding":"17.6.6","matchCriteriaId":"1B2179D2-0545-4DEB-8B56-16299D22E171"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:catalyst_9800_embedded_wireless_controller_firmware:*:*:*:*:*:*:*:*","versionStartIncluding":"17.8.0","versionEndExcluding":"17.9.4","matchCriteriaId":"53EA3BC3-D2DF-48E4-AEBB-B4DE252F1D9D"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:catalyst_9800_embedded_wireless_controller:-:*:*:*:*:*:*:*","matchCriteriaId":"78706517-83F4-4D44-A6EC-B78ADCEABAC0"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:business_150ax_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"10.6.2.0","matchCriteriaId":"E877AC2A-766E-476C-8173-F31BBB32C7CE"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:business_150ax:-:*:*:*:*:*:*:*","matchCriteriaId":"AB2B555E-1523-4C62-A91D-EE1F3F1200EC"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:business_151axm_firmware:*:*:*:*:*:*:*:*","versionEndExcluding":"10.6.2.0","matchCriteriaId":"B98D3109-7D15-4736-890A-A4798C4CF08D"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:business_151axm:-:*:*:*:*:*:*:*","matchCriteriaId":"8760865B-4AB3-4A1A-960D-FF6974A7AC06"}]}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-dos-capwap-DDMCZS4m","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ap-dos-capwap-DDMCZS4m","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
