EUVD-2021-14229 | Rockwell Automation Connected Components Workbench v12.00.00 and prior does not limit the objects that can be deserialized. This vulnerability allows attackers to craft a malicious serialized object that, if opened by a local user in Connected Components Workbench, may result in remote code execution. This vulnerability requires user interaction to be successfully exploited. |
Solution
Rockwell Automation recommends users of the affected software update to an available software revision (Connected Components Workbench v13.00.00 or later) that addresses the associated risk.
Workaround
Users who are unable to update are directed towards risk mitigation strategies provided below, and are encouraged, when possible, to combine these with Rockwell Automation’s general security guidelines to employ multiple strategies simultaneously. If upgrade is not possible, Rockwell Automation recommends deploying the following mitigations: Run Connected Components Workbench as a User, not as an Administrator, to minimize the impact of malicious code on the infected system. Do not open untrusted .ccwarc, files with Connected Components Workbench. Employ training and awareness programs to educate users on the warning signs of a phishing or social engineering attack. Use of Microsoft AppLocker or other similar allow list applications can help mitigate risk. Information on using AppLocker with Rockwell Automation products is available at KnowledgeBase Article QA17329 (login required). Ensure the least-privilege user principle is followed, and user/service account access to shared resources (such as a database) is only granted with a minimum number of rights as needed. For more information, please see the industrial security advisory from Rockwell Automation.
