Vulnerability in TVU Networks Receiver/Transceiver devices running firmware (CVE-2026-104075)
Summary
Vulnerability in TVU Networks Receiver/Transceiver devices running firmware (CVE-2026-104075). Successful exploitation can lead to full system takeover. Exploitable via POST /tvu/Login.
Original description
The description as published by the source.
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.
