CVE-2026-87674
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，系统日志守护进程存在本地权限提升漏洞。由于内部进程间通信（IPC）通道上的访问控制不足，允许未提权的本地用户提交格式错误的日志配置。在生成配置文件时，由于缺乏适当的输入清理机制，攻击者可注入任意指令，这些指令在日志服务重新加载时将以 elevated 权限执行，从而导致本地权限提升。

Source: CVE Program / CVE List V5
Vulnerability Description
A local privilege escalation vulnerability exists in the system logging daemon of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. Insufficient access controls on internal inter-process communication (IPC) channels allow an unprivileged local user to submit malformed logging configurations. Due to improper input sanitization during configuration file generation, an attacker can inject arbitrary directives that execute with elevated privileges when the logging service reloads, leading to local privilege escalation.
