CVE-2023-28399
As a result, the user may be able to destroy the system and/or execute a malicious program.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.18%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Incorrect permission assignment for critical resource exists in CONPROSYS HMI System (CHS) versions prior to 3.5.3. ACL (Access Control List) is not appropriately set to the local folder where the affected product is installed, therefore a wide range of privileges is permitted to a user of the PC where the affected product is installed. As a result, the user may be able to destroy the system and/or execute a malicious program.
