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，该漏洞源于针对依赖RSA进行密钥交换的密码组的布莱臣巴赫攻击的对策执行不当造成的。攻击者可利用该漏洞可以通过向设备发送精心设计的TLS消息来利用这个漏洞，执行加密分析操作，从而可以解密先前捕获的TLS会话到受影响的设备。

英文描述:

A vulnerability in the TLS handler of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 1000 Series firewalls could allow an unauthenticated, remote attacker to gain access to sensitive information. The vulnerability is due to improper implementation of countermeasures against the Bleichenbacher attack for cipher suites that rely on RSA for key exchange. An attacker could exploit this vulnerability by sending crafted TLS messages to the device, which would act as an oracle and allow the attacker to carry out a chosen-ciphertext attack. A successful exploit could allow the attacker to perform cryptanalytic operations that may allow decryption of previously captured TLS sessions to the affected device. To exploit this vulnerability, an attacker must be able to perform both of the following actions: Capture TLS traffic that is in transit between clients and the affected device Actively establish a considerable number of TLS connections to the affected device
