The vulnerability is due to improper input validation for certain fields of specific SSL/TLS messages. An attacker could exploit this vulnerability by sending a malformed SSL/TLS message through an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. No manual intervention is needed to recover the device after it has reloaded."},{"lang":"es","value":"Una vulnerabilidad en la inspección SSL/TLS de Cisco Firepower Threat Defense (FTD) Software para los firewalls Cisco Firepower Serie 2100 podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad es debido a una comprobación de entrada inapropiada para determinados campos de mensajes SSL/TLS específicos. Un atacante podría explotar esta vulnerabilidad mediante el envío de un mensaje SSL/TLS malformado por medio de un dispositivo afectado. Una explotación con éxito podría permitir a un atacante causar que el dispositivo afectado se recargue, resultando en una condición de DoS. No es requerida una intervención manual para recuperar el dispositivo después de que se haya recargado"}],"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:C/C:N/I:N/A:H","baseScore":8.6,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":4.0}],"cvssMetricV30":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.0","vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","baseScore":8.6,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"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:C","baseScore":7.1,"accessVector":"NETWORK","accessComplexity":"MEDIUM","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"COMPLETE"},"baseSeverity":"HIGH","exploitabilityScore":8.6,"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-119"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-119"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense:6.3.0:*:*:*:*:*:*:*","matchCriteriaId":"3ED58B0E-FCC7-48E3-A5C0-6CC54A38BAE3"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense:6.4.0:*:*:*:*:*:*:*","matchCriteriaId":"B2DF0B07-8C2A-4341-8AFF-DE7E5E5B3A43"},{"vulnerable":true,"criteria":"cpe:2.3:a:cisco:firepower_threat_defense:6.5.0:*:*:*:*:*:*:*","matchCriteriaId":"41E168ED-D664-4749-805E-77644407EAFE"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_2110:-:*:*:*:*:*:*:*","matchCriteriaId":"52D96810-5F79-4A83-B8CA-D015790FCF72"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_2120:-:*:*:*:*:*:*:*","matchCriteriaId":"16FE2945-4975-4003-AE48-7E134E167A7F"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_2130:-:*:*:*:*:*:*:*","matchCriteriaId":"DCE7122A-5AA7-4ECD-B024-E27C9D0CFB7B"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_2140:-:*:*:*:*:*:*:*","matchCriteriaId":"976901BF-C52C-4F81-956A-711AF8A60140"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-ssl-dcrpt-dos-RYEkX4yy","source":"psirt@cisco.com","tags":["Vendor Advisory"]},{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ftd-ssl-dcrpt-dos-RYEkX4yy","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]}]}}]}
