Description
Docker Desktop Community Edition before 2.1.0.1 allows local users to gain privileges by placing a Trojan horse docker-credential-wincred.exe file in %PROGRAMDATA%\DockerDesktop\version-bin\ as a low-privilege user, and then waiting for an admin or service user to authenticate with Docker, restart Docker, or run 'docker login' to force the command.
