CVE-2026-104075: TVU Networks Receiver/Transceiver Authentication Bypass via /tvu/Login
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.

Event History
Frequently Asked Questions
Which systems are affected?
TVU Networks Receiver/Transceiver devices running firmware earlier than version 7.9 are affected. The exposed component is the device web management interface.
What does an attacker need to exploit this issue?
An attacker only needs network access to the web management login endpoint. No credentials, user interaction, or valid password are required; the attacker can submit an empty or omitted UserName parameter to POST /tvu/Login.
What access can successful exploitation provide?
Successful exploitation returns a valid administrative session cookie. This gives the attacker full administrative control of the device's web management interface.
How can administrators determine whether a device may be vulnerable?
Check the device firmware version. Devices running a version before 7.9 may be vulnerable, particularly if their web management interface is reachable by untrusted networks.
