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.", "affected": [ { "vendor": "Cisco", "product": "Cisco Firepower Threat Defense Software", "defaultStatus": "unknown", "versions": [ { "version": "6.2.3.14", "status": "affected" }, { "version": "6.4.0.1", "status": "affected" }, { "version": "6.2.3.7", "status": "affected" }, { "version": "6.2.3", "status": "affected" }, { "version": "6.4.0.2", "status": "affected" }, { "version": "6.2.3.9", "status": "affected" }, { "version": "6.2.3.1", "status": "affected" }, { "version": "6.2.3.2", "status": "affected" }, { "version": "6.4.0.5", "status": "affected" }, { "version": "6.2.3.10", "status": "affected" }, { "version": "6.4.0", "status": "affected" }, { "version": "6.4.0.3", "status": "affected" }, { "version": "6.2.3.6", "status": "affected" }, { "version": "6.4.0.4", "status": "affected" }, { "version": "6.2.3.15", "status": "affected" }, { "version": "6.2.3.5", "status": "affected" }, { "version": "6.2.3.4", "status": "affected" }, { "version": "6.2.3.3", "status": "affected" }, { "version": "6.2.3.8", "status": "affected" }, { "version": "6.4.0.6", "status": "affected" }, { "version": "6.2.3.11", "status": "affected" }, { "version": "6.2.3.12", "status": "affected" }, { "version": "6.2.3.13", "status": "affected" }, { "version": "6.4.0.7", "status": "affected" }, { "version": "6.4.0.8", "status": "affected" }, { "version": "6.6.0", "status": "affected" }, { "version": "6.4.0.9", "status": "affected" }, { "version": "6.2.3.16", "status": "affected" }, { "version": "6.6.0.1", "status": "affected" }, { "version": "6.6.1", "status": "affected" }, { "version": "6.4.0.10", "status": "affected" }, { "version": "6.7.0", "status": "affected" }, { "version": "6.4.0.11", "status": "affected" }, { "version": "6.6.3", "status": "affected" }, { "version": "6.7.0.1", "status": "affected" }, { "version": "6.6.4", "status": "affected" }, { "version": "6.4.0.12", "status": "affected" }, { "version": "6.7.0.2", "status": "affected" }, { "version": "7.0.0", "status": "affected" }, { "version": "6.2.3.17", "status": "affected" }, { "version": "7.0.0.1", "status": "affected" }, { "version": "6.6.5", "status": "affected" }, { "version": "7.0.1", "status": "affected" }, { "version": "7.1.0", "status": "affected" }, { "version": "6.4.0.13", "status": "affected" }, { "version": "6.6.5.1", "status": "affected" }, { "version": "6.2.3.18", "status": "affected" }, { "version": "7.0.1.1", "status": "affected" }, { "version": "6.7.0.3", "status": "affected" }, { "version": "6.4.0.14", "status": "affected" }, { "version": "7.1.0.1", "status": "affected" }, { "version": "6.6.5.2", "status": "affected" }, { "version": "7.0.2", "status": "affected" }, { "version": "6.4.0.15", "status": "affected" }, { "version": "7.2.0", "status": "affected" }, { "version": "7.0.2.1", "status": "affected" }, { "version": "7.0.3", "status": "affected" }, { "version": "6.6.7", "status": "affected" }, { "version": "7.1.0.2", "status": "affected" }, { "version": "7.2.0.1", "status": "affected" }, { "version": "7.0.4", "status": "affected" }, { "version": "7.2.1", "status": "affected" }, { "version": "7.0.5", "status": "affected" }, { "version": "6.4.0.16", "status": "affected" }, { "version": "7.3.0", "status": "affected" }, { "version": "7.2.2", "status": "affected" }, { "version": "7.2.3", "status": "affected" }, { "version": "6.6.7.1", "status": "affected" }, { "version": "7.3.1", "status": "affected" }, { "version": "7.1.0.3", "status": "affected" }, { "version": "7.2.4", "status": "affected" }, { "version": "7.0.6", "status": "affected" }, { "version": "7.2.5", "status": "affected" }, { "version": "7.2.4.1", "status": "affected" }, { "version": "7.3.1.1", "status": "affected" }, { "version": "7.4.0", "status": "affected" }, { "version": "6.4.0.17", "status": "affected" }, { "version": "7.0.6.1", "status": "affected" }, { "version": "7.2.5.1", "status": "affected" }, { "version": "7.4.1", "status": "affected" }, { "version": "7.4.1.1", "status": "affected" }, { "version": "6.6.7.2", "status": "affected" }, { "version": "6.4.0.18", "status": "affected" }, { "version": "7.2.5.2", "status": "affected" }, { "version": "7.3.1.2", "status": "affected" } ] } ] } } }
