Exposure is likely limited to Windows hosts running 2345 Security Guard 3.7 with the 2345NetFirewall.sys driver present.

Prioritize cleanup where the product is deployed on shared or business-critical Windows systems. Mitigation focus: Inventory systems for 2345 Security Guard 3.7 and 2345NetFirewall.sys.; Check vendor guidance for a fixed release or supported remediation.; Remove or disable the vulnerable product or driver where not required..
