An elevation of privilege vulnerability exists in Microsoft Project when Microsoft Project Server does not properly manage user sessions. For this Cross-site Request Forgery(CSRF/XSRF) vulnerability to be exploited, the victim must be authenticated to (logged on) the target site. (CVE-2017-11876)
A remote code execution vulnerability exists when a user opens a specially crafted office file. (ADV170020).
