Description · from the CVE record

TVU Networks Receiver/Transceiver devices running firmware before version 7.9 contain an authentication bypass vulnerability in the web management login endpoint POST /tvu/Login that allows remote unauthenticated attackers to obtain an administrative session by submitting an empty or absent UserName parameter. Attackers can send a crafted HTTP request directly, bypassing client-side JavaScript validation, to receive a valid session cookie regardless of the password value and gain full administrative control of the device's web management interface.
