中文描述:

Cisco ASA（Adaptive Security Appliances，自适应安全设备）Software是美国思科（Cisco）公司的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 ASA Software 9.6(2.1)之前的版本中的Identity Firewall功能存在缓冲区溢出漏洞。远程攻击者可通过发送特制的NetBIOS数据包利用该漏洞执行任意代码，完全控制系统或造成受影响的系统重载。运行Cisco ASA Software的以下产品受到影响：Cisco ASA 5500 Series Adaptive Security Appliances，Cisco ASA 5500-X Series Next-Generation Firewalls，Cisco Catalyst 6500 Series/7600 Series ASA Services Module，Cisco ASA 1000V Cloud Firewall，Cisco Adaptive Security Virtual Appliance，Cisco ASA for Firepower 9300 Series，Cisco ASA for Firepower 4100 Series，Cisco ISA 3000 Industrial Security Appliance。

英文描述:

A vulnerability in the Identity Firewall feature of Cisco ASA Software before 9.6(2.1) could allow an unauthenticated, remote attacker to cause a reload of the affected system or to remotely execute code. The vulnerability is due to a buffer overflow in the affected code area. An attacker could exploit this vulnerability by sending a crafted NetBIOS packet in response to a NetBIOS probe sent by the ASA software. An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or cause a reload of the affected system. Note: Only traffic directed to the affected system can be used to exploit this vulnerability. This vulnerability affects systems configured in routed and transparent firewall mode and in single or multiple context mode. This vulnerability can be triggered by IPv4 traffic.
