Summary
generated automatically from NVD dataDocker before 1.3.1 and docker-py before 0.5.3 retry over plain HTTP when an HTTPS connection to the registry fails. A man-in-the-middle attacker positioned between the client and the registry can block HTTPS traffic to force this downgrade. The attacker could then obtain authentication data and image data. The CVSS v2.0 score is 5.0 (MEDIUM), reflecting a partial confidentiality impact.
NVD 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.
