CVE - Mitigation Options

Saw on a post regarding the CVE, it recommended:
  • Disable file upload functionality if not actively used.
  • Implement WAF rules to block suspicious file uploads
Our users never need to send attachments, upload files, or use the File Storage area. Is there a way to disable upload functionality on older builds? Thanks.

What if you create a firewall rule that only allows trusted IPs to access the server using a browser. Anyone outside the organization would not be able to access webmail via browser. Does this help mitigate this vulnerability?

Just trying to identify steps to block these attacks on older builds until they can be upgraded.
