CVE-2026-87663

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，交换机间远程执行服务存在身份验证绕过和命令注入漏洞。在处理跨交换架构（fabric）的远程命令执行 IPC 帧时，接收交换机在未经适当验证传输参数的情况下，以高权限处理级别执行这些命令。这允许位于同一交换架构内某个交换机上的攻击者提升权限，并在本地或已启用远程执行功能的其他受管交换架构成员上执行任意 root 命令。

Vulnerability Title
N/A
Source: CVE Program / CVE List V5
Vulnerability Description
An authentication bypass and command injection vulnerability exists in the inter-switch remote execution service of Brocade Fabric OS versions before 9.2.2d and 10.0.0 through 10.0.0a1. When processing remote command execution IPC frames across the fabric, the receiving switch processes these commands at an elevated processing level without proper verification of transmitted parameters. This allows an attacker on a single fabric-connected switch to escalate privileges and execute arbitrary root commands locally or across other managed fabric members where remote execution functionality is enabled.
