中文描述:

Cisco Adaptive Security Appliance（ASA）5500-X Series with FirePOWER Services等都是美国思科（Cisco）公司的安全设备。Firepower System Software是使用在其中的一套防火墙操作系统。 Cisco Firepower System Software（运行在Cisco Firepower Threat Defense (FTD)传感器上）中的Sourcefire tunnel control channel协议存在权限许可和访问控制漏洞，该漏洞源于受影响的软件对CLI命令没有执行充分的检测。本地攻击者可通过对Firepower传感器和Cisco FMC进行身份验证，然后向Cisco FMC或借助Cisco FMC向其他Firepower传感器发送CLI命令利用该漏洞修改设备配置或删除文件。以下产品受到影响：Cisco Adaptive Security Appliance (ASA) 5500-X Series with FirePOWER Services；Adaptive Security Appliance (ASA) 5500-X Series Next-Generation Firewalls；FirePOWER 7000 Series Appliances；FirePOWER 8000 Series Appliances；Firepower 2100 Series Security Appliances；Firepower 4100 Series Security Appliances；Firepower 9300 Series Security Appliances；Firepower Management Center；Firepower Threat Defense；Firepower Threat Defense Virtual (FTDv)；Virtual Next-Generation Intrusion Prevention System (NGIPSv)。

英文描述:

A vulnerability in the Sourcefire tunnel control channel protocol in Cisco Firepower System Software running on Cisco Firepower Threat Defense (FTD) sensors could allow an authenticated, local attacker to execute specific CLI commands with root privileges on the Cisco Firepower Management Center (FMC), or through Cisco FMC on other Firepower sensors and devices that are controlled by the same Cisco FMC. To send the commands, the attacker must have root privileges for at least one affected sensor or the Cisco FMC. The vulnerability exists because the affected software performs insufficient checks for certain CLI commands, if the commands are executed via a Sourcefire tunnel connection. An attacker could exploit this vulnerability by authenticating with root privileges to a Firepower sensor or Cisco FMC, and then sending specific CLI commands to the Cisco FMC or through the Cisco FMC to another Firepower sensor via the Sourcefire tunnel connection. A successful exploit could allow the attacker to modify device configurations or delete files on the device that is running Cisco FMC Software or on any Firepower device that is managed by Cisco FMC.
