      "value": "A vulnerability in the Cisco Network Plug and Play agent, also referred to as the Cisco Open Plug-n-Play agent, of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a memory leak on an affected device. The vulnerability is due to insufficient input validation by the affected software. An attacker could exploit this vulnerability by sending invalid data to the Cisco Network Plug and Play agent on an affected device. A successful exploit could allow the attacker to cause a memory leak on the affected device, which could cause the device to reload."

Esta vulnerabilidad también se debe a la insuficiente validación de entrada por parte del software afectado. Un atacante podría explotar esta vulnerabilidad mediante el envío de datos inválidos al agente Cisco Network Plug and Play en un dispositivo afectado. Su explotación con éxito podría permitir que el atacante provoque una fuga de memoria en el dispositivo afectado, lo que podría provocar el reinicio del dispositivo."
