Vulnerability Title
RustDesk Missing Session Scope Enforcement Allows Out-of-Scope Control Message Injection
Source: CVE Program / CVE List V5
Vulnerability Description
RustDesk before 1.4.9 does not enforce a session's authorized connection scope on the server side, so a peer granted a limited session type (FileTransfer, PortForward, ViewCamera, or Terminal) can send control messages and login options reserved for a full Remote session. An authenticated remote peer can exploit this missing scope check to act outside its granted scope, injecting out-of-scope control messages to observe and control the host beyond the permissions it was given.
