"value": "A vulnerability in the Cisco Discovery Protocol implementation for Cisco Video Surveillance 8000 Series IP Cameras could allow an unauthenticated, adjacent attacker to cause an affected IP camera to reload. 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)."

"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 un paquete de Cisco Discovery Protocol malicioso hacia una c\u00e1mara IP afectada. Una explotaci\u00f3n con \u00e9xito podr\u00eda permitir al atacante hacer que la c\u00e1mara IP afectada se recargue inesperadamente, resultando en una condici\u00f3n de denegaci\u00f3n de servicio (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 (Capa 2 adyacente)."
