Omron CX-Position
Plan Patch7.8ICS-CERT ICSA-22-088-02Mar 29, 2022
Attack VectorLocal
Auth RequiredNone
ComplexityLow
User InteractionRequired
Summary
Omron CX-Position versions 2.5.3 and earlier contain memory corruption vulnerabilities (buffer overflow, use-after-free) in NCI file parsing. Successful exploitation when parsing a malicious NCI file could allow code execution on the affected system.
What this means
What could happen
An attacker with local access could execute arbitrary code on a CX-Position workstation by crafting a malicious NCI file, potentially compromising engineering settings and process parameters for motion control systems.
Who's at risk
This affects engineering teams and operators who use Omron CX-Position software to program and configure motion control systems. Typical users include automation engineers managing Omron motion controllers in manufacturing, conveyor systems, and robotic applications.
How it could be exploited
An attacker must first obtain local access to a machine running CX-Position and deliver a malicious NCI file to the user. When the user opens or processes the NCI file in CX-Position, the memory corruption vulnerabilities are triggered, allowing code execution in the context of the application.
Prerequisites
- Local access to CX-Position workstation
- User interaction to open or parse a malicious NCI file
- CX-Position version 2.5.3 or earlier installed

Remediation & Mitigation
0/4
Do now
0/1WORKAROUNDRestrict file access and implement controls to prevent users from opening untrusted NCI files from external sources
Schedule — requires maintenance window
0/1Patching may require device reboot — plan for process interruption
HOTFIXUpdate CX-Position to version 2.5.4 or later if available through Omron Auto Update or by contacting Omron technical support
Long-term hardening
0/2HARDENINGImplement network segmentation to limit access to engineering workstations running CX-Position from general user networks
HARDENINGEstablish a file validation and scanning process for NCI files before they are processed by CX-Position
