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.
Brocade Fabric OS 9.2.2d 之前版本以及 10.0.0 至 10.0.0a1 版本中，在时间和区域管理子系统存在操作系统命令注入漏洞。当通过 REST API 或配置下载例程更新系统时区设置时，系统在将输入值传递给底层 Shell 执行例程进行处理之前，未能对其进行适当的清理（sanitize）。具有低权限管理员访问身份的认证用户，可以通过提交包含 Shell 元字符的恶意构造的时区字符串来利用此漏洞。成功利用该漏洞后，攻击者能够逃逸受限的管理环境，并以提升的权限执行任意 Shell 命令。

Vulnerability Description
An OS command injection vulnerability exists in the time and zone management subsystem of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When updating system timezone settings via the REST API or configuration download routines, the system fails to sanitize input values before processing them in underlying shell execution routines. An authenticated user with low-privilege administrative access can exploit this vulnerability by submitting a crafted timezone string containing shell metacharacters. Successful exploitation allows the attacker to escape the restricted management environment and execute arbitrary shell commands with elevated privileges.
