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 6.4.0版本至6.4.0.8版本（release）中的TLS 1.3版本策略（配置有URL category）存在安全漏洞。远程攻击者可通过发送特制的TLS 1.3连接请求利用该漏洞绕过TLS 1.3版本策略，访问受影响设备之外的URL。
英文描述:
A vulnerability in the Transport Layer Security version 1.3 (TLS 1.3) policy with URL category functionality for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass a configured TLS 1.3 policy to block traffic for a specific URL. The vulnerability is due to a logic error with Snort handling of the connection with the TLS 1.3 policy and URL category configuration. An attacker could exploit this vulnerability by sending crafted TLS 1.3 connections to an affected device. A successful exploit could allow the attacker to bypass the TLS 1.3 policy and access URLs that are outside the affected device and normally would be dropped.
