Descriptions

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

Connected Components Workbench (versiones v13.00.00 y anteriores), ISaGRAF Workbench (versiones v6.0 hasta v6.6.9), y Safety Instrumented System Workstation (versiones v1.2 y anteriores (para Trusted Controllers)) no limitan los objetos que pueden ser deserializados. Esto permite a atacantes diseñar un objeto serializado malicioso que, si es abierto por un usuario local en Connected Components Workbench, puede resultar en una ejecución de código arbitrario. Esta vulnerabilidad requiere la interacción del usuario para ser explotada con éxito

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Rockwell Automation Connected Components Workbench. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of CCWARC files. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process.
