CVE-2020-3255 (CNNVD-202005-218)
中文标题:
Cisco Firepower Threat Defense 资源管理错误漏洞
英文标题:
Cisco Firepower Threat Defense Software Packet Flood Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Firepower Threat Defense（FTD）是美国思科（Cisco）公司的一套提供下一代防火墙服务的统一软件。 Cisco FTD Software中的数据包处理功能存在资源管理错误漏洞，该漏洞源于低效的内存管理。远程攻击者可通过高频率发送IPv4或IPv6流量利用该漏洞造成拒绝服务。
英文描述:
A vulnerability in the packet processing functionality of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to inefficient memory management. An attacker could exploit this vulnerability by sending a high rate of IPv4 or IPv6 traffic through an affected device. This traffic would need to match a configured block action in an access control policy. An exploit could allow the attacker to cause a memory exhaustion condition on the affected device, which would result in a DoS for traffic transiting the device, as well as sluggish performance of the management interface. Once the flood is stopped, performance should return to previous states.
