CVE-2026-87678

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 版本之前的网络管理界面中存在一个输入验证与输出编码漏洞。在配置联邦认证（Federated Authentication, FA）时，系统未对身份提供商（Identity Provider, IdP）的签发者参数进行清理。已认证的管理员——或能够在导入流程中提供精心构造的 FA 配置文件攻击者——可以注入任意 Web 服务器指令。这可能导致服务拒绝，例如阻止 Web 管理守护进程启动，或者可能篡改 Web 服务器的安全控制措施。

Vulnerability Description
An input validation and output encoding vulnerability exists in the web management interface of Brocade Fabric OS versions before 10.0.1. When configuring Federated Authentication (FA), the system fails to sanitize the Identity Provider (IdP) issuer parameter. An authenticated administrator—or an attacker capable of supplying crafted FA configuration files during an import routine—can inject arbitrary web server directives. This can lead to service denial by preventing the web management daemon from starting, or potentially alter web server security controls.
