CVE-2022-1118: Rockwell Automation ISaGRAF Deserialization of Untrusted Data

Severity: high (CVSS 7.8 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 11.1% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2022-05-17 · updated 2026-06-17
Weakness: CWE-502

Description

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

Rockwell Automation Connected Component Workbench: through 13.00.00
Rockwell Automation ISaGRAF Workbench: from 6.0 through 6.6.9
Rockwell Automation Safety Instrumented Systems Workstation: through 1.2
