Man-in-the-Middle (MitM)
CVE-2014-5277 · GHSA-8w94-cf6g-c8mg
- Affected
- PyPI docker-py < 0.5.3
- Fixed in
- 0.5.3· Vendor fix available
- Issue
- 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.
Recommended action: Upgrade to 0.5.3 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
