The vulnerability is due to improper implementation of countermeasures against the Bleichenbacher attack for cipher suites that rely on RSA for key exchange. An attacker could exploit this vulnerability by sending crafted TLS messages to the device, which would act as an oracle and allow the attacker to carry out a chosen-ciphertext attack. A successful exploit could allow the attacker to perform cryptanalytic operations that may allow decryption of previously captured TLS sessions to the affected device. To exploit this vulnerability, an attacker must be able to perform both of the following actions: Capture TLS traffic that is in transit between clients and the affected device Actively establish a considerable number of TLS connections to the affected device"},{"lang":"es","value":"Una vulnerabilidad en el manejador TLS de Cisco Adaptive Security Appliance (ASA) Software y Cisco Firepower Threat Defense (FTD) Software para los firewalls Cisco Firepower 1000 Series, podría permitir a un atacante remoto no autenticado obtener acceso a información confidencial. La vulnerabilidad es debido a una implementación inapropiada de contramedidas contra el ataque Bleichenbacher para conjuntos de cifrado que dependen de RSA para el intercambio de claves. Un atacante podría explotar esta vulnerabilidad mediante el envío de mensajes TLS diseñados hacia el dispositivo, que actuaría como un oráculo y permitiría a un atacante conducir un ataque de texto cifrado elegido. Una explotación con éxito podría permitir a un atacante realizar operaciones criptoanalíticas que podrían habilitar el descifrado de sesiones TLS capturadas previamente en el dispositivo afectado. Para aprovechar esta vulnerabilidad, un atacante necesita ser capaz de realizar ambas de las siguientes acciones: Capturar el tráfico TLS que esta en transito entre clientes y el dispositivo afectado que establece Activamente un número considerable de conexiones TLS hacia el dispositivo afectado"}],"metrics":{"cvssMetricV31":[{"source":"psirt@cisco.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","baseScore":5.3,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":1.4},{"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:L/I:N/A:N","baseScore":3.7,"baseSeverity":"LOW","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.2,"impactScore":1.4}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:M/Au:N/C:P/I:N/A:N","baseScore":4.3,"accessVector":"NETWORK","accessComplexity":"MEDIUM","authentication":"NONE","confidentialityImpact":"PARTIAL","integrityImpact":"NONE","availabilityImpact":"NONE"},"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-203"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-203"}]}],"configurations":[{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*","versionEndExcluding":"6.4.0.10","matchCriteriaId":"07C5999A-6647-424E-A093-60D36561ACE7"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*","versionStartIncluding":"6.5.0","versionEndExcluding":"6.5.0.5","matchCriteriaId":"38DCBF6C-AA34-4A5B-B2B1-57684DD5BB42"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6.0","versionEndExcluding":"6.6.1","matchCriteriaId":"3F0C6D76-9652-4EE6-9CA2-96BFBB469539"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1000:-:*:*:*:*:*:*:*","matchCriteriaId":"E6F79864-CA70-4192-AC2C-E174DF3F25B2"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1010:-:*:*:*:*:*:*:*","matchCriteriaId":"7FFE3880-4B85-4E23-9836-70875D5109F7"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1120:-:*:*:*:*:*:*:*","matchCriteriaId":"727A02E8-40A1-4DFE-A3A2-91D628D3044F"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1140:-:*:*:*:*:*:*:*","matchCriteriaId":"19F6546E-28F4-40DC-97D6-E0E023FE939B"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1150:-:*:*:*:*:*:*:*","matchCriteriaId":"EB3B0EC3-4654-4D90-9D41-7EC2AD1DDF99"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:adaptive_security_appliance_software:*:*:*:*:*:*:*:*","versionEndExcluding":"9.13.1.13","matchCriteriaId":"6BB7D8DC-2652-4108-8574-12C4AFF0B93C"},{"vulnerable":true,"criteria":"cpe:2.3:o:cisco:adaptive_security_appliance_software:*:*:*:*:*:*:*:*","versionStartIncluding":"9.14","versionEndExcluding":"9.14.1.30","matchCriteriaId":"A5E49F5A-F8E9-4D0D-A58F-9F5BB5F0C9EE"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1000:-:*:*:*:*:*:*:*","matchCriteriaId":"E6F79864-CA70-4192-AC2C-E174DF3F25B2"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1010:-:*:*:*:*:*:*:*","matchCriteriaId":"7FFE3880-4B85-4E23-9836-70875D5109F7"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1120:-:*:*:*:*:*:*:*","matchCriteriaId":"727A02E8-40A1-4DFE-A3A2-91D628D3044F"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1140:-:*:*:*:*:*:*:*","matchCriteriaId":"19F6546E-28F4-40DC-97D6-E0E023FE939B"},{"vulnerable":false,"criteria":"cpe:2.3:h:cisco:firepower_1150:-:*:*:*:*:*:*:*","matchCriteriaId":"EB3B0EC3-4654-4D90-9D41-7EC2AD1DDF99"}]}]}],"references":[{"url":"https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-tls-bb-2g9uWkP","source":"psirt@cisco.com","tags":["Patch","Vendor
