Rockwell Automation ISaGRAF Runtime Versions 4.x and 5.x searches for and loads DLLs as dynamic libraries. Uncontrolled loading of dynamic libraries could allow a local, unauthenticated attacker to execute arbitrary code. This vulnerability only affects ISaGRAF Runtime when running on Microsoft Windows systems.

Rockwell Automation recommends users update to ISaGRAF Runtime 5 Version 5.72.00. End users are encouraged to restrict or block access on TCP 1131 and TCP 1132 from outside the industrial control system. Confirm the least-privilege user principle is followed and user/service account access to Runtime's folder location is granted with a minimum amount of rights needed. Rockwell Automation recommends users of affected versions evaluate the mitigations provided and apply the appropriate mitigations to deployed products. Users are encouraged to combine this guidance with the general security guidelines for a comprehensive defense-in-depth strategy. To reduce risk, Rockwell Automation recommends users: Employ proper network segmentation and security controls. Minimize network exposure for all control system devices. Locate control systems behind firewalls. Isolate control systems from other networks when possible. Refer to the Converged Plantwide Ethernet (CPwE) Design and Implementation Guide for best practices deploying network segmentation and broader defense-in-depth strategies. Consider using proper network infrastructure controls, such as firewalls, UTM devices, VPN, or other security appliances. Ensure the least-privilege user principle is followed, and user/service account access to Runtime’s folder location is granted with a minimum amount of rights, as needed. Please see publications from Rockwell Automation and Schneider Electric, Xylem, or contact GE for further information about how to mitigate these vulnerabilities in additional affected products.
