An attacker could exploit this vulnerability by sending a large amount of TCP/IP network traffic through the affected device. A successful exploit could allow the attacker to cause the Cisco FTD device to drop network traffic, resulting in a DoS condition. The affected device must be rebooted to resolve the DoS condition." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "Uncontrolled Resource Consumption",
