Remote Desktop Services Remote Code Execution Vulnerability

A remote code execution vulnerability exists in Remote Desktop Services – formerly known as Terminal Services – when an authenticated attacker abuses clipboard redirection. An attacker who successfully exploited this vulnerability could execute arbitrary code on the victim system. 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 must already have compromised a system running Remote Desktop Services, and then wait for a victim system to connect to Remote Desktop Services.

The update addresses the vulnerability by correcting how Remote Desktop Services handles clipboard redirection.
