To exploit this vulnerability, the attacker must be able to access an associated Cisco SD-WAN vEdge device. This vulnerability is due to insufficient authorization checks. An attacker could exploit this vulnerability by sending crafted HTTP requests to the web-based messaging service interface of an affected system. A successful exploit could allow the attacker to gain unauthenticated read and write access to the affected vManage system. With this access, the attacker could access information about the affected vManage system, modify the configuration of the system, or make configuration changes to devices that are managed by the system."},{"lang":"es","value":"Una vulnerabilidad en la interfaz de servicio de mensajería basada en web de Cisco SD-WAN vManage Software podría permitir a un atacante adyacente no autenticado omitir la autenticación y autorización y modificar la configuración de un sistema afectado. Para explotar esta vulnerabilidad, el atacante debe poder acceder a un dispositivo Cisco SD-WAN vEdge asociado. Esta vulnerabilidad es debido a controles de autorización insuficientes. Un atacante podría explotar esta vulnerabilidad mediante el envío de peticiones HTTP diseñadas para la interfaz del servicio de mensajería basada en web de un sistema afectado. Una explotación con éxito podría permitir al atacante obtener acceso de lectura y escritura no autenticada al sistema vManage afectado. Con este acceso, el atacante podría acceder a información sobre el sistema vManage afectado, modificar la configuración del sistema, o hacer cambios de la configuración para dispositivos que son administrados por el sistema"}],"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:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9},{"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:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:A/AC:L/Au:N/C:P/I:P/A:P","baseScore":5.8,"accessVector":"ADJACENT_NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":6.5,"impactScore":6.4,"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-Other"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:catalyst_sd-wan_manager:*:*:*:*:*:*:*:*","versionStartIncluding":"20.4","versionEndExcluding":"20.4.1","matchCriteriaId":"C2D155FE-14C5-4658-A5D4-974DCE7FED4F"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:catalyst_sd-wan_manager:*:*:*:*:*:*:*:*","versionStartIncluding":"20.5","versionEndExcluding":"20.5.1","matchCriteriaId":"BE2C4782-DD4D-4113-A367-13DA609AD5F4"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:sd-wan_vmanage:*:*:*:*:*:*:*:*","versionEndExcluding":"20.3.1","matchCriteriaId":"E6F0246B-3913-42E8-85D8-9FD746D0E1AF"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdw-auth-bypass-65aYqcS2","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sdw-auth-bypass-65aYqcS2","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
