The attacker would need to have valid administrator credentials. The vulnerability is due to incorrect input validation of the HTTP URL used to establish a connection to the LSC Certificate Authority (CA). An attacker could exploit this vulnerability by authenticating to the targeted device and configuring a LSC certificate. An exploit could allow the attacker to cause a DoS condition due to an unexpected restart of the device."},{"lang":"es","value":"Una vulnerabilidad en la administración de Locally Significant Certificate (LSC) para el controlador de LAN inalámbrica (WLC) de Cisco podría permitir que un atacante remoto identificado  que el dispositivo se reinicie inesperadamente, lo que provoca una condición de Denegación de Servicio (DoS). El atacante necesitaría tener credenciales de administrador válidas. La vulnerabilidad se debe a una comprobación de entrada incorrecta de la URL HTTP utilizada para establecer una conexión con la Certificate Authority (CA) de LSC. Un atacante podría explotar esta vulnerabilidad autenticándose en el dispositivo de destino y configurando un certificado LSC. Una vulnerabilidad podría permitir al atacante generar una condición DoS debido a un reinicio inesperado del dispositivo."}],"metrics":{"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","baseScore":4.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.2,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","baseScore":4.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.2,"impactScore":3.6}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:L/Au:S/C:N/I:N/A:C","baseScore":6.8,"accessVector":"NETWORK","accessComplexity":"LOW","authentication":"SINGLE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"COMPLETE"},"baseSeverity":"MEDIUM","exploitabilityScore":8.0,"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":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:wireless_lan_controller_software:*:*:*:*:*:*:*:*","versionEndExcluding":"8.3.150.0","matchCriteriaId":"EE718013-03C2-4E22-B377-C6DA6036CE70"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:wireless_lan_controller_software:*:*:*:*:*:*:*:*","versionStartIncluding":"8.5.131.0","versionEndExcluding":"8.5.140.0","matchCriteriaId":"5CE0F82C-DBC2-4037-8CBA-6568E7E478EF"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:wireless_lan_controller_software:*:*:*:*:*:*:*:*","versionStartIncluding":"8.6.101.0","versionEndExcluding":"8.8.100.0","matchCriteriaId":"5CC94C06-408A-4C51-8AB9-E756C8EA649D"}]}]}],"references":[{"url":"http://www.securityfocus.com/bid/108028","source":"psirt@cisco.com","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-wlc-cert-dos","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"http://www.securityfocus.com/bid/108028","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Third Party Advisory","VDB Entry"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190417-wlc-cert-dos","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
