CVE-2026-87685

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 之前版本以及 10.0.0 至 10.0.0a1 版本中，WebTools 管理接口存在任意文件操作漏洞。在处理配置传输请求时，该应用程序未能正确验证和清理用户提供的状态文件路径参数。经过身份验证的管理员用户可以通过提交精心构造的状态文件参数来利用此漏洞，导致底层进程将任意系统文件移动到可预测的、对所有用户可读的临时目录中。这可能引发持久的拒绝服务（DoS）、关键系统文件破坏、主机被入侵或敏感数据泄露。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
An arbitrary file manipulation vulnerability exists in the WebTools management interface of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When processing configuration transfer requests, the application fails to properly validate and sanitize a user-supplied status file path parameter. An authenticated administrative user can exploit this issue by submitting a specially crafted status file parameter, causing the underlying process to move an arbitrary system file to a predictable, world-readable temporary directory. This can lead to persistent Denial of Service (DoS), critical system file destruction, host compromise, or sensitive data leakage.
