-- Mitigation:
Given the requirements for users to have access to their email, and given the nature of the vulnerabilities discovered in the PineApp Mail-SeCure software, the only salient mitigation strategy is to restrict access to port 7443 of the PineApp device or VM to those machines which have a legitimate need to access the PineApp software directly. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. For systems running Microsoft Windows, these features are available in the native Windows Firewall, as described in http://technet.microsoft.com/en-us/library/cc725770%28WS.10%29.aspx and numerous other Microsoft Knowledge Base articles.
