Brocade Fabric OS
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
博科（Brocade）Fabric 操作系统在 9.2.2d 之前的版本，以及 10.0.0 至 10.0.0a1 版本中，对特定下载协议的处理存在缺陷，使用了未经过清理的参数字符串。在处理升级请求时，这些参数会被转换为系统命令字符串，并通过系统 shell 接口执行。由于如主机名或文件路径等字段中的控制字符和 shell 元字符未被剥离或清理，攻击者可以利用固件管理守护进程（firmware management daemon）的高权限执行任意 shell 命令。

Vulnerability Description
Brocade Fabric versions before 9.2.2d and 10.0.0 through 10.0.0a1 handling of specific download protocols utilizes unsanitized parameter strings. When processing upgrade requests, parameters are converted into system command strings and executed through a system shell interface. Because control characters and shell metacharacters in fields like the host or file path are not stripped or sanitized, an attacker can execute arbitrary shell commands with the firmware management daemon's elevated privileges.
