The com.threeis.webta.H402editUser servlet processes crafted account identifiers, passwords, and role fields to assign administrative privileges despite the caller's delegated role. Timekeeper, Master Timekeeper, or HR Admin access is required, and successful exploitation grants administrative control within the application.
