The vulnerability exists because the affected software improperly manages resources when processing inbound Live Data traffic. An attacker could exploit this vulnerability by sending multiple crafted Live Data packets to an affected device. A successful exploit could cause the affected device to run out of buffer resources, which could result in a stack overflow and cause the affected device to reload, resulting in a DoS condition. Note: The Live Data port in Cisco Unified Contact Center Enterprise devices allows only a single TCP connection. To exploit this vulnerability, an attacker would have to send crafted packets to an affected device before a legitimate Live Data client establishes a connection."}, {"lang": "es", "value": "Una vulnerabilidad en el servidor Live Data de Cisco Unified Contact Center Enterprise, podr\u00eda permitir a un atacante remoto no autenticado causar una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado.
