CVE-2018-12608: Mobyproject Moby

High severity, CVSS 7.5. EPSS: 0.9% chance of exploitation in the next 30 days.

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.

Affected products

• Mobyproject Moby: before 17.06.0 (fixed in 17.06.0)
