Apply Secure Serialization Settings
To fully mitigate the risk of exploit, the following configuration changes must be implemented after all server and client nodes have been upgraded to compatible versions that support the fix:

Server Components:
• Change “BinarySerializer” -> “Mode” setting from ‘Binary Formatter’ to ‘Json’.
• Change “BinarySerializer” -> “AcceptBinaryFormattedData” setting from ‘true’ to ‘false’.
• Re-cache the XOS Event Handlers assembly

Client Components:
• Configure clients/products that interface with Enterprise SCADA to only use JSON serialization.

HMI:
• Migrate HMI displays

For step-by-step instructions on where and how to apply these configuration settings, how to migrate HMI displays, compatible server-client versions list, and additional details please refer to KB117814 “AVEVA Midstream Product Bulletin – Removal of Binary Formatter”." } ] }, { "lang": "en", "value": "AVEVA recommends that customers using affected product versions should perform the following to mitigate the risk of exploit:\n * Evaluate the impact of these vulnerabilities based on your operational environment, architecture, and product implementation.\n * Plan an upgrade of Servers and Clients to one of the available fixed versions listed in section “Security Updates”.\n * Configure Servers and Clients as described in section “Apply Secure Serialization Settings”.", "supportingMedia": [ { "type": "text/html", "base64": false, "value": "AVEVA recommends that customers using affected product versions should perform the following to mitigate the risk of exploit:
