WIN-911 2021 R1 and R2 are vulnerable to a permissions misconfiguration that may allow an attacker to locally write files to the program Operator Workspace directory, which holds DLL files and executables. A low-privilege attacker could write a malicious DLL file to the Operator Workspace directory to achieve privilege escalation and the permissions of the user running the program.
Solution:
During installation, installed file permissions are set to allow anyone to modify those files.
