These vulnerabilities are due to missing checks when the IP cameras process a Cisco Discovery Protocol packet. An attacker could exploit these vulnerabilities by sending a malicious Cisco Discovery Protocol packet to the targeted IP camera. A successful exploit could allow the attacker to execute code on the affected IP camera or cause it to reload unexpectedly, resulting in a denial of service (DoS) condition. Note: Cisco Discovery Protocol is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent)." }, { "lang": "es", "value": "M\u00faltiples vulnerabilidades en la implementaci\u00f3n del Protocolo de Descubrimiento de Cisco para las C\u00e1maras IP de Vigilancia por Video de la Serie 8000 de Cisco podr\u00edan permitir que un atacante adyacente no autenticado ejecutara el c\u00f3digo de forma remota o causara una recarga de una c\u00e1mara IP afectada. Estas vulnerabilidades se deben a la falta de comprobaciones cuando las c\u00e1maras IP procesan un paquete del Protocolo Cisco Discovery. Un atacante podr\u00eda explotar estas vulnerabilidades enviando un paquete de Protocolo de Descubrimiento Cisco malicioso a la c\u00e1mara IP objetivo. Un exploit exitoso podr\u00eda permitir al atacante ejecutar c\u00f3digo en la c\u00e1mara IP afectada o hacer que se recargue inesperadamente, resultando en una condici\u00f3n de denegaci\u00f3n de servicio (DoS).
