Inosoft VisiWin is a completely open system with a configurable range of
functions. It combines all features of classic HMI software with
unlimited programming possibilities.
The installation of the solution will create insecure folder, and this
could allow a malicious user to manipulate file content or change
legitimate files (e.g., VisiWin7.Server.Manager.exe which runs with
SYSTEM privileges) to compromise a system or to gain elevated
privileges.
This is the list of insecure files and folders with their respective
permissions:
