CVE-2022-1118

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.

Does this matter?

EPSS puts the probability of exploitation in the next 30 days at 11.1%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.

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
