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 10.0.1 之前版本中，REST API 管理组件存在多个基于栈的缓冲区溢出漏洞。在处理 API 请求载荷（例如设备配置属性或端口映射请求）时，REST API 服务未能正确验证传入的数组计数和字符串长度与内部缓冲区容量之间的匹配性。拥有 REST API 访问权限的已认证攻击者可以发送精心构造的超大请求参数，从而引发执行栈上的内存损坏。这可能导致拒绝服务状况（守护进程崩溃）或管理进程上下文中的任意代码执行。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
Multiple stack-based buffer overflow vulnerabilities exist in the REST API management component of Brocade Fabric OS versions prior to 10.0.1. When processing API request payloads (such as device configuration attributes or port mapping requests) the REST API service fails to properly validate incoming array counts and string lengths against internal buffer capacities. An authenticated attacker with REST API access can transmit crafted, oversized request parameters to induce memory corruption on the execution stack. This may result in a denial-of-service condition (daemon crash) or potential arbitrary code execution within the management process context.
