New Lotus Notes Vulnerability -- but to what?

There is a newly reported vulnerabiltiy -- [Full-Disclosure] Lotus Notes URL argument injection vulnerability that will allow a web page to issue additional options to the notes:// URL. The iDefense site explains how Notes can be started with a UNC share. I doubt very many companies are allowing UNC shares through their firewalls. The part that seems like a stretch is:

The attacker can create a malicious DLL containing arbitrary code that will be loaded and executed when notes.exe is starting up.

Could this really happen?

Attackers can be inside the firewall. They can be employees, or they can be outsiders who have gained access through a Microsoft security flaw, through an emailed trojan horse, etc.
