AI-suggested
Organizations should immediately assess their deployment of Copeland LP E3 Supervisory Control systems and verify firmware versions, prioritizing upgrades to version 2.31F01 or later once available. Until patches are released, network segmentation should be enforced to isolate supervisory control systems from untrusted networks and limit access to trusted administrators only. Implement strict access controls and monitor authentication logs for unusual hash usage or repeated authentication attempts. Employ network intrusion detection systems (NIDS) tuned to detect anomalous authentication patterns or hash replay attempts. Where possible, enforce multi-factor authentication (MFA) at the network or application layer to reduce reliance on password hashes alone. Additionally, conduct regular security audits and penetration testing focused on ICS environments to identify potential exploitation paths. Vendor engagement is critical to obtain timely patches or workarounds. Finally, educate operational technology (OT) personnel about the risks of password hash exposure and the importance of secure credential handling.
Description
E3 Site Supervisor Control (firmware version < 2.31F01) application services (MGW and RCI) uses client side hashing for authentication. An attacker can authenticate by obtaining only the password hash.
