The vulnerability is due to insufficient validation when Ethernet frames are processed. An attacker could exploit this vulnerability by sending malicious Ethernet frames through an affected device. A successful exploit could allow the attacker do either of the following: Fill the /ngfw partition on the device: A full /ngfw partition could result in administrators being unable to log in to the device (including logging in through the console port) or the device being unable to boot up correctly. Note: Manual intervention is required to recover from this situation. Customers are advised to contact the Cisco Technical Assistance Center (TAC) to help recover a device in this condition. Cause a process crash: The process crash would cause the device to reload. No manual intervention is necessary to recover the device after the reload."}, {"lang": "es", "value": "Una vulnerabilidad en la ruta de procesamiento de paquetes de entrada de Cisco Firepower Threat Defense (FTD) Software para interfaces que est\u00e1n configuradas como Inline Pair o en modo Passive podr\u00eda permitir a un atacante adyacente no autenticado causar una condici\u00f3n de denegaci\u00f3n de servicio (DoS). La vulnerabilidad es debido a una comprobaci\u00f3n insuficiente cuando son procesadas las tramas Ethernet. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de tramas Ethernet maliciosas por medio de un dispositivo afectado. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir a un atacante causar una de las siguientes acciones: Llenar la partici\u00f3n /ngfw en el dispositivo: una partici\u00f3n /ngfw completa podr\u00eda resultar en que los administradores no puedan iniciar sesi\u00f3n en el dispositivo (incluido el inicio de sesi\u00f3n por medio del puerto de la consola) o el dispositivo no puede arrancar correctamente. Nota: Se requiere una intervenci\u00f3n manual para recuperarse de esta situaci\u00f3n. Se recomienda a los clientes que se comuniquen con el Cisco Technical Assistance Center (TAC) para ayudar a recuperar un dispositivo en esta condici\u00f3n. Causar un bloqueo del proceso: el bloqueo del proceso har\u00eda que el dispositivo se recargara. No es necesaria ninguna intervenci\u00f3n manual para recuperar el dispositivo despu\u00e9s de la recarga"}], "lastModified": "2021-10-19T14:46:55.840", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "CB4FADF7-A3CD-44B4-85DF-75F28369B459", "versionEndExcluding": "6.3.0.6"}, {"criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "53C69C8B-5A19-4613-8861-683CF21806B7", "versionEndExcluding": "6.4.0.10", "versionStartIncluding": "6.4.0"}, {"criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3ED0E59C-146C-494F-AD46-F6FB43F9C575", "versionEndExcluding": "6.5.0.5", "versionStartIncluding": "6.5.0"}, {"criteria": "cpe:2.3:a:cisco:firepower_threat_defense:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "754010DE-2C33-4BA1-9567-90C46309B664", "versionEndExcluding": "6.6.1", "versionStartIncluding": "6.6.0"}], "operator": "OR"}]}], "sourceIdentifier": "ykramarz@cisco.com"}
