The primary mitigation for CVE-2024-32987 is to upgrade Microsoft SharePoint Server to version 16.0.17328.20424 or later. Before applying the update, it's recommended to review Microsoft's documentation for any potential compatibility issues or breaking changes. Consider testing the update in a non-production environment first. If immediate patching is not possible, review SharePoint permissions and access controls to minimize the potential impact of a successful attack. Implement network segmentation to limit access to SharePoint servers. After the upgrade, verify the fix by attempting to reproduce the vulnerability using known attack patterns (if available) or by reviewing SharePoint logs for any suspicious activity.
