TeamViewer Security Flaw Lets Controlled Computers Attack Support Staff

TeamViewer has resolved a vulnerability that allows a controlled computer to attack the system that connected to support it. A compromised or malicious host machine can exploit the issue to crash the viewer application and potentially execute unauthorized commands on the controller device. Businesses must update TeamViewer promptly to prevent support staff systems from being targeted during remote sessions.
