Summary
Rockwell Automation OptixPanel products contain a privilege escalation vulnerability (CWE-269) that may allow users to exfiltrate credentials and escalate privileges. Affected versions: 2800S OptixPanel Standard 4.0.0.350, 2800C OptixPanel Compact 4.0.0.325, and Embedded Edge Compute Module 4.0.0.347. The vulnerability has high attack complexity and requires user interaction.
What this means
What could happen
An attacker could obtain administrator credentials and escalate privileges on OptixPanel devices, potentially gaining control over the HMI and any connected industrial processes or sensors it manages.
Who's at risk
Manufacturing and process plants using Rockwell Automation OptixPanel as their human-machine interface (HMI) are affected, particularly those running the 2800S Standard, 2800C Compact, or Embedded Edge Compute Module variants. Water utilities, power generation, chemical plants, and food processing facilities that rely on these OptixPanel products for operator interface and control visibility should prioritize patching.
How it could be exploited
An attacker would need to trick a user into interacting with a malicious payload or compromised interface (requires user interaction and high attack complexity). Once successful, the attacker can exfiltrate credentials stored on the OptixPanel and escalate to higher privilege levels, allowing manipulation of the HMI application and underlying connected devices.
Prerequisites
- User interaction required (user must click or accept a malicious action)
- Access to OptixPanel interface or ability to present a social engineering attack to an OptixPanel user
- Network access to the OptixPanel device

Remediation & Mitigation
0/6
Do now
0/1HARDENINGEnsure OptixPanel devices are not directly accessible from the internet; restrict network access to trusted engineering workstations and control network segments only
Schedule — requires maintenance window
0/3Patching may require device reboot — plan for process interruption
HOTFIXUpdate 2800S OptixPanel Standard to firmware version 4.0.2.123 or later
HOTFIXUpdate 2800C OptixPanel Compact to firmware version 4.0.2.116 or later
HOTFIXUpdate Embedded Edge Compute Module to firmware version 4.0.2.106 or later
Long-term hardening
0/2HARDENINGIsolate OptixPanel devices and their connected control networks from business networks with a firewall
HARDENINGIf remote access to OptixPanel is required, use a VPN connection rather than exposing the device directly to untrusted networks
