CVE-2022-45794

7.5 (High)


                        
                          CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

CWE-306 - Missing Authentication for Critical Function

Vendor Fix OMRON recommends users take the following mitigation measures to minimize the risk of exploitation of these vulnerabilities.

Vendor Fix Enable the FINS write protection function.

Vendor Fix Minimize connection of control systems and equipment to open networks preventing untrusted devices from accessing them.

Vendor Fix Implement firewalls:

Vendor Fix Shut down unused communications ports

Vendor Fix Limit communications hosts

Vendor Fix Limit access to FINS port (9600)

Vendor Fix Isolate control systems and equipment from the IT network.

Vendor Fix Use a virtual private network (VPN) for remote access to control systems and equipment.

Vendor Fix Use strong passwords and change them frequently.

Vendor Fix Install physical controls, only permitting authorized personnel access to control systems and equipment.

Vendor Fix Use malware scanning tools to ensure safety of any USB drives or other portable devices before connecting them to control systems and devices.

Vendor Fix Enforce multifactor authentication on all devices with remote access to control systems and equipment when possible.

Vendor Fix Protect hosts with access to the control system against malware and Ensure installation and maintenance of up-to-date, antivirus software on hosts with access to control systems.

Vendor Fix Complete validation processing, such as backup and range checks, to cope with unintentional modification of input/output data to control systems and devices.

Vendor Fix Complete periodical data backup and maintenance to prepare for data loss.
