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 Firepower Threat Defense（FTD）和Cisco Adaptive Security Appliances Software（ASA Software） SSL/TLS Denial存在安全漏洞，该漏洞源于配置为使用对象组搜索的受影响设备对网络请求的处理不当。攻击者可以通过向受影响的设备发送特制的网络请求来利用此漏洞。成功的利用可能允许攻击者绕过设备上的访问控制列表 (ACL) 规则，绕过安全保护，并将网络流量发送到未经授权的主机。

英文描述:

A vulnerability in the identity-based firewall (IDFW) rule processing feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass security protections. This vulnerability is due to improper handling of network requests by affected devices configured to use object group search. An attacker could exploit this vulnerability by sending a specially crafted network request to an affected device. A successful exploit could allow the attacker to bypass access control list (ACL) rules on the device, bypass security protections, and send network traffic to unauthorized hosts.
