CVE-2026-87671

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 10.0.1 之前的版本中，Web 管理守护程序存在一个越界内存读取漏洞。未经验的 HTTP 端点在处理特定 URL 查询参数时，未对数组索引边界进行验证，也未执行数值范围检查。未经认证的远程攻击者可通过发送单个包含查询字符串中极端数值的精心构造的 HTTP 请求来利用此漏洞。这会导致无效的内存解引用，引发 Web 管理进程崩溃（拒绝服务），并可能导致管理平面短暂中断。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
An out-of-bounds memory read vulnerability exists in the web management daemon of Brocade Fabric OS versions before 10.0.1. Unauthenticated HTTP endpoints process specific URL query parameters without validating array index boundaries or performing numerical range checks. An unauthenticated remote attacker can exploit this issue by sending a single, crafted HTTP request containing extreme numerical values in the query string. This causes an invalid memory dereference, resulting in a crash of the web management process (Denial of Service) and potential temporary management-plane disruption.
