To exploit this vulnerability, an attacker would need to have valid Administrator credentials on the affected device.\r\n \r\nThis vulnerability is due to improper validation of user input that is in incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted HTTP request to the web-based management interface of the affected device. A successful exploit could allow the attacker to cause an unexpected reload of the device, resulting in a DoS condition."
