Summary
Rockwell Automation OptixPanel products contain an improper access control vulnerability (CWE-269) that may allow users to exfiltrate credentials and escalate privileges. Affected versions: 2800C OptixPanel Compact 4.0.0.325, 2800S OptixPanel Standard 4.0.0.350, 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 exfiltrate credentials and escalate privileges on OptixPanel devices, potentially gaining unauthorized control over visualization and automation logic on your network.
Who's at risk
Rockwell Automation OptixPanel Compact, OptixPanel Standard, and Embedded Edge Compute Module operators in water utilities, electric utilities, and other critical infrastructure using these HMI/visualization devices for process monitoring and control.
How it could be exploited
An attacker would need to trick a user with OptixPanel access into performing an action (e.g., opening a malicious link or attachment) or interact with the device in a specific way to trigger the credential exfiltration and privilege escalation. This requires user interaction and has high attack complexity.
Prerequisites
- User interaction required (e.g., social engineering or tricking a user to click a link or open an attachment)
- Network access to the affected OptixPanel device
- Access to a user account on the OptixPanel system
