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.

Nuclio 是一个用于实时事件和数据处理的“无服务器（Serverless）”框架。在 1.17.4 之前的版本中，在 Nuclio 的本地 Docker 平台上，函数命名空间（namespace）会被未经过验证地插入到双引号包裹的 命令中，该命令通过宿主机的 shell（ ）执行。由于默认的身份验证类型为 （即无需认证），远程攻击者可以注入任意操作系统命令，这些命令将以 root 权限在 dashboard 容器内执行。由于该容器持有 Docker socket，因此可能导致宿主机被攻陷。该问题已在 1.17.

Vulnerability Title
Nuclio: Unauthenticated OS command injection via function namespace in docker ps --filter label (local Docker platform)
Source: CVE Program / CVE List V5
Vulnerability Description
Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.17.4, on the Nuclio local Docker platform, the function namespace is interpolated—unvalidated—into a double-quoted docker ps --filter "label=nuclio.io/namespace=<value>" command that is executed via the host shell (/bin/sh -c). Because the default auth kind is nop (unauthenticated), a remote attacker can inject arbitrary OS commands that run as root inside the dashboard container, which holds the Docker socket → host compromise. This issue has been patched in version 1.17.4.
