What are the exploitation ideas for the TeamViewer vulnerability?

For Function A, an attacker can reverse-control the client and potentially hide the desktop display by altering memory data (not implemented in the public POC). For Function B, an attacker can unlock mouse/keyboard controls only if the client had already established a remote connection and the server disabled input. The article advises against converting the POC to a full exploit to limit harm. Read more in the exploitation section.
