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:
