The vulnerability is due to incorrect processing of certain Cisco Discovery Protocol packets. An attacker could exploit this vulnerability by sending certain Cisco Discovery Protocol packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and reload, resulting in a DOS condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent)."}, {"lang": "es", "value": "Una vulnerabilidad en Cisco Discovery Protocol de Cisco Video Surveillance 8000 Series IP Cameras, podr\u00eda permitir a un atacante adyacente no autenticado causar un filtrado de memoria, lo que podr\u00eda conllevar una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado. La vulnerabilidad es debido al procesamiento incorrecto de determinados paquetes de Cisco Discovery Protocol. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de determinados paquetes de Cisco Discovery Protocol hacia un dispositivo afectado. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir al atacante causar que el dispositivo afectado consumiera memoria continuamente, lo que podr\u00eda conllevar a que el dispositivo se bloquee y se recargue, resultando en una condici\u00f3n de DOS. Nota: Cisco Discovery Protocol es un protocolo de Capa 2. Para explotar esta vulnerabilidad, un atacante debe estar en el mismo dominio de transmisi\u00f3n que el dispositivo afectado (adyacente a Capa 2)"}], "lastModified": "2023-11-07T03:22:53.240", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:8000p_ip_camera_firmware:1.0.9-4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "955AED3C-3ED2-4467-AAA5-510521CD56E7"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:cisco:8000p_ip_camera:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "EC586459-C532-4A89-8C43-58DA17181A38"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:8020_ip_camera_firmware:1.0.9-4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "0C59F1EE-2E1C-4001-A9A7-73B92F9827AB"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:cisco:8020_ip_camera:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "B783A438-0D5A-4BA7-97E0-0FA917045B37"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:8030_ip_camera_firmware:1.0.9-4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "DD32F59C-A08D-4692-9F79-5F8F419B5B18"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:cisco:8030_ip_camera:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "42E1CC6F-8A71-4012-ABF8-F0DF96B23949"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:8070_ip_camera_firmware:1.0.9-4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "934836A7-DBBD-44CF-8CE5-28C2FC7AC754"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:cisco:8070_ip_camera:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "BD2510BB-580C-4826-BE9D-4879F2B8BDA5"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:8400_ip_camera_firmware:1.0.9-4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4E28EB73-9705-4BED-9969-50DE456F8B5F"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:cisco:8400_ip_camera:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "12067AE1-9A55-43BE-8C75-849E060AF41A"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:8620_ip_camera_firmware:1.0.9-4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D84B5451-961F-4118-B288-C94CDEC6D40A"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:cisco:8620_ip_camera:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "AA06EF29-7996-4916-90E1-6A569EB95C6B"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:8630_ip_camera_firmware:1.0.9-4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D1397782-897F-44FB-A42D-5BAEF0CDAB77"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:cisco:8630_ip_camera:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "3214D558-A6FF-4B03-947B-40AD12355235"}], "operator": "OR"}], "operator": "AND"}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:8930_speed_dome_ip_camera_firmware:1.0.9-4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "37D529B4-C32B-4DFE-A216-C7A18228DA15"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:cisco:8930_speed_dome_ip_camera:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "39E0E98A-F382-4AA8-B940-78A78C99736A"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "ykramarz@cisco.com"}
