The vulnerability is due to insufficient validation of SSL/TLS messages when the device performs software-based SSL decryption. An attacker could exploit this vulnerability by sending a crafted SSL/TLS message through an affected device. SSL/TLS messages sent to an affected device do not trigger this vulnerability. A successful exploit could allow the attacker to cause a process to crash. This crash would then trigger a reload of the device. No manual intervention is needed to recover the device after the reload."}, {"lang": "es", "value": "Una vulnerabilidad en el controlador de mensajes SSL/TLS basado en software del software Cisco Firepower Threat Defense (FTD) podr\u00eda permitir a un atacante remoto no autenticado activar una recarga de un dispositivo afectado, resultando en una condici\u00f3n de denegaci\u00f3n de servicio (DoS). La vulnerabilidad es debido a una comprobaci\u00f3n insuficiente de los mensajes SSL/TLS cuando el dispositivo lleva a cabo el descifrado SSL basado en software. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de un mensaje SSL/TLS dise\u00f1ado por medio de un dispositivo afectado. Los mensajes SSL/TLS enviados a un dispositivo afectado no desencadenan esta vulnerabilidad. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir al atacante causar el bloqueo de un proceso. Este bloqueo podr\u00eda entonces desencadenar una recarga del dispositivo. No es necesaria una intervenci\u00f3n manual para recuperar el dispositivo despu\u00e9s de la recarga"}], "lastModified": "2024-11-21T05:44:16.410", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0B60D48C-19D8-4015-8D25-D3C0165C6080", "versionEndExcluding": "6.4.0", "versionStartIncluding": "6.3.0"}, {"criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B5432C87-A9AF-4CC8-8573-443562963519", "versionEndExcluding": "6.6.0", "versionStartIncluding": "6.5.0"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:cisco:firepower_threat_defense_virtual:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "A38E373E-438F-44F6-AABF-2C57142507EE"}, {"criteria": "cpe:2.3:h:cisco:asa_5512-x:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "08F0F160-DAD2-48D4-B7B2-4818B2526F35"}, {"criteria": "cpe:2.3:h:cisco:asa_5515-x:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "977D597B-F6DE-4438-AB02-06BE64D71EBE"}, {"criteria": "cpe:2.3:h:cisco:asa_5525-x:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "EB71EB29-0115-4307-A9F7-262394FD9FB0"}, {"criteria": "cpe:2.3:h:cisco:asa_5545-x:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "57179F60-E330-4FF0-9664-B1E4637FF210"}, {"criteria": "cpe:2.3:h:cisco:asa_5555-x:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "5535C936-391B-4619-AA03-B35265FC15D7"}, {"criteria": "cpe:2.3:h:cisco:firepower_1010:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "7FFE3880-4B85-4E23-9836-70875D5109F7"}, {"criteria": "cpe:2.3:h:cisco:firepower_1120:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "727A02E8-40A1-4DFE-A3A2-91D628D3044F"}, {"criteria": "cpe:2.3:h:cisco:firepower_1140:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "19F6546E-28F4-40DC-97D6-E0E023FE939B"}, {"criteria": "cpe:2.3:h:cisco:firepower_1150:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "EB3B0EC3-4654-4D90-9D41-7EC2AD1DDF99"}, {"criteria": "cpe:2.3:h:cisco:firepower_2110:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "52D96810-5F79-4A83-B8CA-D015790FCF72"}, {"criteria": "cpe:2.3:h:cisco:firepower_2120:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "16FE2945-4975-4003-AE48-7E134E167A7F"}, {"criteria": "cpe:2.3:h:cisco:firepower_2130:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "DCE7122A-5AA7-4ECD-B024-E27C9D0CFB7B"}, {"criteria": "cpe:2.3:h:cisco:firepower_2140:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "976901BF-C52C-4F81-956A-711AF8A60140"}, {"criteria": "cpe:2.3:h:cisco:isa_3000:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "9510E97A-FD78-43C6-85BC-223001ACA264"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "ykramarz@cisco.com"}
