Docker Desktop before 4.17.0 allows an unprivileged user to bypass Enhanced Container Isolation restrictions via the raw Docker socket and launch privileged containers

Docker Desktop before 4.17.0 allows an unprivileged user to bypass Enhanced Container Isolation (ECI) restrictions by setting the Docker host to docker.raw.sock, or npipe:////.pipe/docker_engine_linux on Windows, via the -H (--host) CLI flag or the DOCKER_HOST environment variable and launch containers without the additional hardening features provided by ECI. This would not affect already running containers, nor containers launched through the usual approach (without Docker's raw socket). The affected functionality is available for Docker Business customers only and assumes an environment where users are not granted local root or Administrator privileges. This issue has been fixed in Docker Desktop 4.17.0. Affected Docker Desktop versions: from 4.13.0 before 4.17.0.

Docker Desktop 安全漏洞

Docker Desktop是美国Docker公司的一个基于容器技术的用于轻量化部署应用的桌面软件。该产品可提供桌面环境可支持在Linux/Windows/Mac OS系统上创建一个容器（轻量级虚拟机）并部署和运行应用程序，以及通过配置文件实现应用程序的自动化安装、部署和升级。 Docker Desktop 4.17.0之前版本存在安全漏洞，该漏洞源于允许非特权用户通过-H CLI 标志或 DOCKER_HOST 环境变量来启动容器，而不使用 ECI 提供的额外强化功能。
