The vulnerability is due to insufficient input validation of SCTP traffic. An attacker could exploit this vulnerability by leveraging a man-in-the-middle position between the eNodeB and the MME and then sending a crafted SCTP message to the MME. A successful exploit would cause the MME to stop sending SCTP messages to the eNodeB, triggering a DoS condition."},{"lang":"es","value":"Una vulnerabilidad en la implementación del Stream Control Transmission Protocol (SCTP) en Cisco Mobility Management Entity (MME), podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un eNodeB que esté conectado en un dispositivo afectado. La vulnerabilidad es debido a una comprobación de entrada insuficiente del tráfico SCTP. Un atacante podría explotar esta vulnerabilidad mediante el aprovechamiento de una posición de tipo man-in-the-middle entre el eNodeB y el MME y luego enviar un mensaje SCTP diseñado hacia el MME. Una explotación con éxito causaría que el MME dejara de enviar mensajes SCTP hacia el eNodeB, desencadenando una condición DoS."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":5.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.2,"impactScore":3.6}],"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H","baseScore":6.8,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.2,"impactScore":4.0}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:M/Au:N/C:N/I:N/A:P","baseScore":4.3,"accessVector":"NETWORK","accessComplexity":"MEDIUM","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":8.6,"impactScore":2.9,"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":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:staros:*:*:*:*:*:*:*:*","versionEndExcluding":"21.16.1","matchCriteriaId":"E162D2B8-7240-4287-AEC9-FBEC680A1E73"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:asr_5000:-:*:*:*:*:*:*:*","matchCriteriaId":"746254AC-B039-432C-AA5C-A82260E57AD7"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:asr_5500:-:*:*:*:*:*:*:*","matchCriteriaId":"301681DF-2A9E-4A91-9918-4A46153ADC01"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:asr_5700:-:*:*:*:*:*:*:*","matchCriteriaId":"A9EF0299-16A7-446D-855D-BFF91EE65534"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200108-mme-dos","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200108-mme-dos","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
