Summary
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.
