Microsoft has outlined the details, here is what they said:
An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server or client. To exploit the vulnerability against a server, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv3 server. To exploit the vulnerability against a client, an unauthenticated attacker would need to configure a malicious SMBv3 server and convince a user to connect to it.
