How to Fix CVE-2018-12608

To remediate this vulnerability, upgrade all affected Github.com/docker/docker dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/docker/docker fixed: 17.06.0-ce 
Upgrade github.com/docker/docker to 17.06.0-ce
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/docker/docker

How to Check if You Are Affected

To determine whether your application is affected by CVE-2018-12608, inspect your project dependencies for Github.com/docker/docker:

inspect dependencies for github.com/docker/docker

Analyze the terminal output to locate any version of Github.com/docker/docker in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 17.06.0-ce), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-288: Authentication Bypass Using an Alternate Path or Channel, where the product requires authentication, but the product has an alternate path or channel that does not require authentication. In Github.com/docker/docker, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

An issue was discovered in Docker Moby before 17.06.0. The Docker engine validated a client TLS certificate using both the configured client CA root certificate and all system roots on non-Windows systems. This allowed a client with any domain validated certificate signed by a system-trusted root CA (as opposed to one signed by the configured CA root certificate) to authenticate.
