Microsoft SharePoint Server Remote Code Execution Vulnerability

According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution? This attack requires a client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.

How could an attacker exploit the vulnerability? In a network-based attack, an attacker authenticated as at least a Site Owner, could write arbitrary code to inject and execute code remotely on the SharePoint Server.
