I can't find this cpe inside the NVD NIST dictionary, rather I read:
microsoft:office
microsoft:office_365
microsoft:office_365_proplus
Can you verify?
 VulDB Community Team2 years ago
Indeed, this disclosure is odd. It looks like Microsoft means Office 365 Plus editions. At the moment we have assigned the most generic microsoft:office_365 and will update as soon as more information is available.
