CVE-2022-1118: Rockwellautomation Connected Component Workbench

High severity, CVSS 7.8. EPSS: 11.1% chance of exploitation in the next 30 days.

Connected Components Workbench (v13.00.00 and prior), ISaGRAF Workbench (v6.0 though v6.6.9), and Safety Instrumented System Workstation (v1.2 and prior (for Trusted Controllers)) do not limit the objects that can be deserialized. This allows attackers to craft a malicious serialized object that, if opened by a local user in Connected Components Workbench, may result in arbitrary code execution. This vulnerability requires user interaction to be successfully exploited

Affected products

• Rockwellautomation Connected Component Workbench: up to and including 13.00.00
• Rockwellautomation Isagraf Workbench: from 6.0, up to and including 6.6.9
• Rockwellautomation Safety Instrumented Systems Workstation: up to and including 1.2
