The version of TeamViewer installed on the remote Windows host upto 13.1.1548 stores a password in Unicode format within TeamViewer.exe process memory between ‘[00 88]’ and ‘[00 00 00]’ delimiters, which might make it easier for attackers to obtain sensitive information by leveraging an unattended workstation on which TeamViewer has disconnected but remains running.
