CVE-2020-3529 (CNNVD-202010-1158)
中文标题:
Cisco Firepower Threat Defense和Cisco Adaptive Security Appliances Software 资源管理错误漏洞
英文标题:
Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software SSL VPN Direct Memory Access Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Firepower Threat Defense（FTD）和Cisco Adaptive Security Appliances Software（ASA Software）都是美国思科（Cisco）公司的产品。Cisco Firepower Threat Defense是一套提供下一代防火墙服务的统一软件。Cisco Adaptive Security Appliances Software是一套防火墙和网络安全平台。该平台提供了对数据和网络资源的高度安全的访问等功能。 Cisco Adaptive Security Appliance (ASA) 和 Cisco Firepower Threat Defense (FTD) 存在安全漏洞，该漏洞源于在SSL VPN连接的协商阶段，直接内存访问(DMA)内存管理效率低下造成的。攻击者可利用该漏洞重新加载受影响的设备，从而导致拒绝服务(DoS)状态。
英文描述:
A vulnerability in the SSL VPN negotiation process for Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to inefficient direct memory access (DMA) memory management during the negotiation phase of an SSL VPN connection. An attacker could exploit this vulnerability by sending a steady stream of crafted Datagram TLS (DTLS) traffic to an affected device. A successful exploit could allow the attacker to exhaust DMA memory on the device and cause a DoS condition.
