Quick assessment

Affected
F5 NGINX Gateway Fabric
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.

描述 当 NGINX Gateway Fabric 配置了 Gateway 自定义资源定义（CRD），并与 NGINX Agent 建立了经过身份验证的 gRPC 连接时，存在安全风险。拥有命名空间权限的身份验证攻击者，如果能够访问某个服务账户，即可冒充该经过身份验证的 NGINX Agent gRPC 连接，从而读取其他命名空间中 Gateway 部署的 TLS 私钥。 影响 远程身份验证攻击者可能能够读取其他命名空间中 Gateway 部署的 TLS 私钥。 本漏洞仅影响控制平面，不涉及数据平面，因此不存在数据
