Microsoft Remote Desktop Client CVE-2020-0611 Remote Code Execution Vulnerability

Description

A remote code execution vulnerability exists in the Windows Remote Desktop Client when a user connects to a malicious server. An attacker who successfully exploited this vulnerability could execute arbitrary code on the computer of the connecting client. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. To exploit this vulnerability, an attacker would need to have control of a server and then convince a user to connect to it. An attacker would have no way of forcing a user to connect to the malicious server, they would need to trick the user into connecting via social engineering, DNS poisoning or using a Man in the Middle (MITM) technique. An attacker could also compromise a legitimate server, host malicious code on it, and wait for the user to connect. The update addresses the vulnerability by correcting how the Windows Remote Desktop Client handles connection requests.
