What happened
TeamViewer Desktop allows for bypass of remote-login access control because the same AES key is used for different customers' installations. If an attacker were to know this key, they could decrypt protected information stored in registry or configuration files or decryption of the Unattended Access password to the system (which allows for remote login to the system).
Who is affected
TeamViewer Desktop. Affected version ranges are listed in the vendor advisory and the NVD entry linked under Sources.
