The vulnerability is due to missing checks when Cisco Discovery Protocol messages are processed. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected IP camera. A successful exploit could allow the attacker to cause the affected IP camera to reload unexpectedly, resulting in a denial of service (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 la implementaci\u00f3n del Cisco Discovery Protocol para Cisco Video Surveillance 8000 Series IP Cameras, podr\u00eda permitir a un atacante adyacente no autenticado causar la recarga de una c\u00e1mara IP afectada. La vulnerabilidad es debido a una falta de comprobaciones cuando los mensajes son procesados desde Cisco Discovery Protocol. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de
