## Overview

WeenyGenius, a computer lab management system developed by Howyar Technologies, has a Missing Authentication vulnerability. Unauthenticated attackers on the same network can easily spoof student or teacher endpoints. Impersonating a student can disrupt normal classroom operations, whereas impersonating a teacher can induce student computers to initiate connections, thereby gaining remote control over the student endpoints.
