MEDIUM5.3EPSS 0.68%Man-in-the-Middle (MitM) in github.com/docker/docker
Published: 11/17/2014Modified: 4/28/2026
Description
Docker before 1.3.1 and docker-py before 0.5.3 fall back to HTTP when the HTTPS connection to the registry fails, which allows man-in-the-middle attackers to conduct downgrade attacks and obtain authentication and image data by leveraging a network position between the client and the registry to block HTTPS traffic.
