CVE-2026-89176: CWE-306 Missing Authentication for Critical Function in Howyar WeenyGenius
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.
AI Analysis
Technical Summary
CVE-2026-89176 describes a Missing Authentication for Critical Function vulnerability in Howyar WeenyGenius. Attackers on the same network can impersonate either student or teacher endpoints without authentication. Impersonating a student disrupts classroom operations, while impersonating a teacher causes student computers to initiate connections, enabling remote control over those endpoints. The vulnerability affects versions from 0 through 12.2.031 inclusive. The CVSS 4.0 vector indicates low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability.
Potential Impact
Unauthenticated attackers on the same network can spoof endpoints to disrupt classroom activities or gain remote control over student computers. This compromises the confidentiality, integrity, and availability of the affected systems, potentially allowing attackers to control student endpoints remotely.
Mitigation Recommendations
No patch or official fix information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict network access to trusted users and monitor for suspicious endpoint spoofing activity.
