FAQ
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 an admin user on the client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.
RCE-Remote Desktop Client
How could an attacker exploit this vulnerability? In the case of a Remote Desktop connection, an attacker with control of a Remote Desktop Server could trigger a remote code execution (RCE) on the RDP client machine when a victim connects to the attacker's server with the vulnerable Remote Desktop Client.
