Episerver Ektron CMS before 9.0 SP3 Site CU 31, 9.1 before SP3 Site CU 45, or 9.2 before SP2 Site CU 22 allows remote attackers to call aspx pages via the activateuser.aspx page, even if a page is located under the /WorkArea/ path, which is forbidden (normally available exclusively for local admins).
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
