The vulnerability relates to the the ability for an attacker to specify a UNC path in the "ReminderSoundFile" property within an email/meeting invite - when the reminder triggers in Outlook, the user's Outlook client attempts to load the sound file specified in the path. If Outlook attempts to initiate an SMB connection to a remote SMB server, it might be possible for the attacker to intercept the user's Net-NTLMv2 hash and relay this to authenticate as the user.
kind of looks fun
