Affected version:
Docker Moby before 17.06.0.

QID Detection Logic(Authenticated):
Vulnerable versions of Docker Moby are detected by running the command "curl --unix-socket /var/run/docker.sock http://localhost/version"

Successful exploitation of vulnerability allows unauthorized modification by an attacker.
