The vulnerability is due to improper validation of specific connection information by the TURN server within the affected software. An attacker could exploit this issue by sending specially crafted network traffic to the affected software. A successful exploit could allow the attacker to send traffic through the affected software to destinations beyond the application, possibly allowing the attacker to gain unauthorized network access."},{"lang":"es","value":"Una vulnerabilidad en el componente servidor Traversal Using Relays around NAT (TURN) del software Cisco Expressway, podría permitir a un atacante remoto no autenticado omitir los controles de seguridad y enviar tráfico de red hacia destinos restringidos. La vulnerabilidad es debido a una comprobación inapropiada de la información de conexión específica por parte del servidor TURN dentro del software afectado. Un atacante podría explotar este problema mediante el envío de tráfico de red especialmente diseñado al software afectado. Una explotación con éxito podría permitir al atacante enviar tráfico por medio del software afectado a destinos más allá de la aplicación, posiblemente permitiendo al atacante conseguir acceso no autorizado a la red"}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":2.5}],"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":2.5}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:L/Au:N/C:P/I:P/A:N","baseScore":6.4,"accessVector":"NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"PARTIAL","availabilityImpact":"NONE"},"baseSeverity":"MEDIUM","exploitabilityScore":10.0,"impactScore":4.9,"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":"CWE-269"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:expressway:*:*:*:*:*:*:*:*","versionEndExcluding":"x12.6.3","matchCriteriaId":"D3F79721-8B07-4843-A265-D8FC85FC9DC3"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:telepresence_video_communication_server:*:*:*:*:*:*:*:*","versionEndExcluding":"x12.6.3","matchCriteriaId":"D63A3260-C96C-4413-8000-AE650038AD85"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-Expressway-8J3yZ7hV","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-Expressway-8J3yZ7hV","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
