漏洞描述
中文描述:

Cisco 3000 Series Industrial Security Appliances（ISR）等都是美国思科（Cisco）公司的安全防火墙设备。Adaptive Security Appliance（ASA）和Firepower Threat Defense（FTD）Software都是使用在Cisco不同安全设备中的防火墙软件。 多款Cisco产品中的ASA和FTD Software存在授权问题漏洞，该漏洞源于程序没有正确的校验SSL客户端凭证。远程攻击者可利用该漏洞建立SSL VPN连接并绕过对SSL证书的校验。以下产品和版本受到影响：Cisco 3000 Series Industrial Security Appliances (ISA)；ASA 5500 Series Adaptive Security Appliances；ASA 5500-X Series Next-Generation Firewalls；ASA Services Module for Cisco Catalyst 6500 Series Switches和Cisco 7600 Series Routers；Adaptive Security Virtual Appliances (ASAv)；Firepower 4110 Security Appliances；Firepower 9300 ASA Security Modules；Adaptive Security Appliance Software 9.4.3.1版本，9.4.3.2版本，9.4.4版本至9.4.4.13版本，9.5.2.7版本，9.5.2.8版本至9.5.3.7版本至9.5.3.9版本，9.6.2.9版本至9.6.2.21版本，9.6.3版本至9.6.3.17版本；Firepower Threat Defense Software 6.0版本至6.0.1.4版本，6.1.0版本至6.1.0.5版本。

英文描述:

A vulnerability in the Secure Sockets Layer (SSL) Virtual Private Network (VPN) Client Certificate Authentication feature for Cisco Adaptive Security Appliance (ASA) could allow an unauthenticated, remote attacker to establish an SSL VPN connection and bypass certain SSL certificate verification steps. The vulnerability is due to incorrect verification of the SSL Client Certificate. An attacker could exploit this vulnerability by connecting to the ASA VPN without a proper private key and certificate pair. A successful exploit could allow the attacker to establish an SSL VPN connection to the ASA when the connection should have been rejected. This vulnerability affects Cisco Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD) Software that is running on the following Cisco products: 3000 Series Industrial Security Appliances (ISA), ASA 5500 Series Adaptive Security Appliances, ASA 5500-X Series Next-Generation Firewalls, ASA Services Module for Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers, Adaptive Security Virtual Appliances (ASAv), Firepower 4110 Security Appliances, Firepower 9300 ASA Security Modules. Cisco Bug IDs: CSCvg40155.
