The Open eClass platform (formerly known as GUnet eClass) is a complete course management system. Prior to version 4.2, a business logic vulnerability allows authenticated students to improperly mark themselves as present in attendance activities, including activities that have already expired, by directly accessing a crafted URL. This issue has been patched in version 4.2.
