Machine automation controller NX7 series all models V1.28 and earlier,
Machine automation controller NX1 series all models V1.48 and earlier,

communication between the controller and the specific software used by
OMRON internally to cause a denial-of-service (DoS) condition or
execute a malicious program.

Omron recommends updating versions of NJ/NX-series machine automation controllers to address this vulnerability. These
updates are available to users by contacting their Omron or distributors:

- NX7-series Machine Automation Controller (All Models): Versions 1.29 or higher 
- NX1-series Machine Automation Controller (All Models): Versions 1.50 or higher 
- NJ-series Machine Automation Controller (NJ501-1300, NJ501-1400, NJ501-1500): Versions 1.49 or higher 
- NJ-series Machine Automation Controller (All other Models): Versions 1.50 or higher

Omron recommends users take the following mitigation measures to minimize the risk of exploitation of this
vulnerability:

Enable antivirus protection:

- Protect any PC with access to the control system against malware by ensuring the installation and maintenance of up-
to-date commercial grade antivirus software protection.

Implement security measures to prevent unauthorized access: 

- Minimize connection of control systems and equipment to open networks preventing untrusted devices from accessing
them.
- Implement firewalls by shutting down unused communications ports, limiting communications between hosts, and isolate
affected systems from the IT network.
- Use a virtual private network (VPN) for remote access to control systems and equipment. 
- Use strong passwords and change passwords frequently. 
- Install physical controls that only permit authorized personnel access to control systems and equipment. 
- Scan USB drives or similar devices for viruses and malware to ensure the devices are safe before connecting them to
systems and devices.
- When possible, enforce multifactor authentication (MFA) on all devices with remote access to control systems and
equipment.

Protect data input and output: 

- Perform process validation, such as backup validation or range checks, to cope with unintentional modification of
input/output data to control systems and devices.

Use data recovery: 

- Conduct periodical data backups and maintenance to prepare for potential data loss.

For more information see Omron’s advisory: OMSR-2022-002 

This vulnerability and countermeasures correspond to the those reported in the CISA ICS Alert: APT Cyber Tools Targeting
ICS/SCADA Devices.");
