CVE intelligence and bounded remediation
CVE-2022-1118 — Rockwellautomation Connected Component Workbench security vulnerability
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

Unsafe deserialization and object reconstruction
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Inventory serialization formats accepted from requests, queues, caches, files, cookies, and cross-service messages.
- Trace whether untrusted input can select classes, types, callbacks, constructors, or object hooks during decoding.
- Identify signing, schema validation, trust-boundary, and compatibility settings for each decoder.
Remediate safely
- Replace native object deserialization with a data-only format and explicit schema validation.
- If replacement is not immediate, use a safe decoder with a minimal type allowlist and disable polymorphic or executable hooks.
- Update the affected library and add inert tests for unknown types, extra fields, malformed nesting, and unsigned data.
