Remediations

• Users using the affected software are encouraged to implement the following steps to invalidate the existing vulnerable private keys/digital certificates and regenerate new secure ones.
• Clear CIP Security configurations from devices and from FactoryTalk Policy Manager (FTPM)
• Update FactoryTalk System Services (FTSS) and FactoryTalk Policy Manager to v6.40.01
• Redeploy CIP Security Policy
• Detailed steps are below:
• 1) Remove deployed security policy from all devices using FTPM: Open FTPM. Document all Zone's security settings and all Conduit's settings as you must re-create them after updating FTPM. Change all devices port's Policies > Zone values to the "Unassigned" Zone. Delete all zones and conduits. Deploy (CIP). Ensure that all endpoints were reset successfully. (migrating from v6.40 only) Deploy (OPC UA). Ensure all endpoints were reset successfully. For any OPC UA clients, perform whatever steps are required by those clients to remove the previously applied certificates. Close FTPM
• Open FTPM.
• Document all Zone's security settings and all Conduit's settings as you must re-create them after updating FTPM.
• Change all devices port's Policies > Zone values to the "Unassigned" Zone.
• Delete all zones and conduits.
• Deploy (CIP). Ensure that all endpoints were reset successfully.
• (migrating from v6.40 only) Deploy (OPC UA). Ensure all endpoints were reset successfully.
• For any OPC UA clients, perform whatever steps are required by those clients to remove the previously applied certificates.
• Close FTPM
• 2) Delete the \FTSS_backup folder: c:\ProgramData\Rockwell\RNAServer\Global\RnaStore\FTSS_Backup
• 3) Delete the \keystore folder: c:\ProgramData\Rockwell Automation\FactoryTalk System Services\keystore
• 4) Delete any backup copies of the \keystore folder. They will be named the same as the \keystore folder but with a suffix appended to it, like: c:\ProgramData\Rockwell Automation\FactoryTalk System Services\ keystore_source_2024_04_25_12_25_38_541566
• 5) Delete the PSKs.json file: c:\ProgramData\Rockwell Automation\FactoryTalk System Services\PSKs.json
• 6) Delete any backup copies of the PSKs.json file. They will be named the same as the PSKs.json file but with a suffix appended to it, like: c:\ProgramData\Rockwell Automation\FactoryTalk System Services\ PSKs.json_source_2024_05_17_07_38_25_200356
• 7) Install FactoryTalk Policy Manager version 6.40.01. Restart the computer when prompted at the end of the install. Open FTPM. FTPM will attempt to connect to the FactoryTalk System Services web server before proceeding. If FTPM could not successfully connect to FactoryTalk System Services (FTSS), it is because the FTSS service hasn't started yet. It will eventually start or else you can start the FTSS service manually in Windows Services.

• 10) Re-create the original Zones.
• 11) Move the devices from the unassigned Zone back to their original zones.
• 12) Re-create the original Conduits.
• 13) Deploy (CIP endpoints).
• 14) (migrating from v6.40 only) Deploy (OPC UA endpoints). For any OPC UA client endpoints, manually apply the newly generated certificates from this deploy.
• For any OPC UA client endpoints, manually apply the newly generated certificates from this deploy.
• Additionally, users are encouraged to implement the suggested security best practices to minimize the risk of vulnerability.
