Omron NS Series HMI Vulnerabilities

Low RiskICS-CERT ICSA-14-203-01Apr 24, 2014
Summary

Omron NS Series HMI devices (NS5, NS8, NS10, NS12, NS15) firmware versions 8.1xx through 8.68x contain cross-site request forgery (CISM-352) and cross-site scripting (CWE-79) vulnerabilities in the web interface. These flaws allow attackers to inject malicious code or force unauthorized actions without proper authentication controls. No vendor patch is currently available for affected firmware versions.

What this means
What could happen
An attacker with network access to an Omron NS Series HMI could inject malicious code into web pages or bypass authentication mechanisms, potentially allowing unauthorized access to control the manufacturing process or alter operator interface displays.
Who's at risk
Manufacturing facilities operating Omron NS5, NS8, NS10, NS12, or NS15 Human-Machine Interfaces (HMIs) used to monitor and control production processes, batch lines, or any automated manufacturing equipment dependent on these touch panels for operator interaction.
How it could be exploited
An attacker sends a specially crafted request over the network to the HMI's web interface. By exploiting cross-site request forgery (CSRF) and cross-site scripting (XSS) flaws, the attacker can inject code that either tricks an authorized operator into performing unintended actions or gains unauthorized access to control functions without proper authentication.
Prerequisites
  • Network access to the HMI's web interface (typically port 80 or 443)
  • HMI running Omron NS Series firmware version 8.1xx through 8.68x
  • For CSRF attacks: the target operator must be logged into the HMI when the attack is delivered

Remediation & Mitigation
0/5
Do now
0/2
HARDENINGRestrict network access to the HMI to only authorized engineering and operations staff using firewall rules or network segmentation
WORKAROUNDDisable or protect the web interface if it is not required for normal operations
Schedule — requires maintenance window
0/1

Patching may require device reboot — plan for process interruption

HOTFIXApply any future security updates from Omron as they become available, and plan replacement or upgrade of NS Series units when possible
Mitigations - no patch available

The following products have reached End of Life with no planned fix: NS15: >=8.1xx|<=8.68x, NS12: >=8.1xx|<=8.68x, NS10: >=8.1xx|<=8.68x, NS8: >=8.1xx|<=8.68x, NS5: >=8.1xx|<=8.68x. Apply the following compensating controls:
HARDENINGPlace the HMI behind a firewall with strict egress/ingress controls and consider air-gapping or VPN access for remote management
HARDENINGMonitor network traffic to and from the HMI for suspicious access patterns
