CVE-2026-87677
Quick assessment
Affected
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.
在 Brocade Fabric OS 9.2.2d 之前的版本以及 10.0.0 至 10.0.0a1 版本中，账户管理子系统存在一个操作系统命令注入漏洞。当管理员执行账户删除操作时，系统会调用内部维护例程，以清理与目标账户关联的加密密钥。由于 Fabric OS 此前接受了格式错误的账户名称，这些名称中可能包含嵌入的 Shell 元字符，从而触发命令注入，导致任意命令执行。

N/A
Source: CVE Program / CVE List V5
Vulnerability Description
An OS command injection vulnerability exists in the account management subsystem of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When an administrator initiates an account deletion, the system invokes an internal maintenance routine to clean up cryptographic keys associated with the target account. Malformed account names previously accepted by Fabric OS can cause the execution of embedded shell metacharacters, triggering command injection.
