### [CVE-2015-1843](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-1843) ![](https://img.shields.io/static/v1?label=Product&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Vulnerability&message=n%2Fa&color=brighgreen) ### Description The Red Hat docker package before 1.5.0-28, when using the --add-registry option, falls 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. NOTE: this vulnerability exists because of a CVE-2014-5277 regression. ### POC #### Reference No PoCs from references. #### Github - https://github.com/xxg1413/docker-security
