CVE-2023-2639

Summary

CVE-2023-2639 is a vulnerability affecting Rockwell Automation's FactoryTalk System Services. The issue lies in the feedback mechanism used to transfer FactoryTalk Policy Manager rules to devices on the network. This mechanism fails to verify the origin of the communication, enabling a threat actor to impersonate a legitimate local client. By visiting a malicious website, an attacker can send a malicious script to the local WebSocket endpoint, gaining access to information such as whether FactoryTact Policy Manager is installed and potentially the entire security policy. This vulnerability poses a significant risk to industrial networks and could lead to unauthorized access and data theft.
