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 inspecci\u00f3n SSL/TLS de Cisco Firepower Threat Defense (FTD) Software para los firewalls Cisco Firepower Serie 2100 podr\u00eda permitir a un atacante remoto no autenticado causar una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado. La vulnerabilidad es debido a una comprobaci\u00f3n de entrada inapropiada para determinados campos de mensajes SSL/TLS espec\u00edficos. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de un mensaje SSL/TLS malformado por medio de un dispositivo afectado. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir a un atacante causar que el dispositivo afectado se recargue, resultando en una condici\u00f3n de DoS. No es requerida una intervenci\u00f3n manual para recuperar el dispositivo despu\u00e9s 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", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH", "baseScore": 8.6, "baseSeverity": "HIGH" }, "exploitabilityScore": 3.9, "impactScore": 4.0 } ], "cvssMetricV30": [ { "source": "ykramarz@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", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "HIGH", "baseScore": 8.6, "baseSeverity": "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", "accessVector": "NETWORK", "accessComplexity": "MEDIUM", "authentication": "NONE", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "availabilityImpact": "COMPLETE", "baseScore": 7.1 }, "baseSeverity": "HIGH", "exploitabilityScore": 8.6, "impactScore": 6.9, "acInsufInfo": false, "obtainAllPrivilege": false, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": false } ] }, "weaknesses": [ { "source": "nvd@nist.gov", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-119" } ] }, { "source": "ykramarz@cisco.com", "type": "Secondary", "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": "ykramarz@cisco.com", "tags": [ "Vendor Advisory" ] } ] }
