Attack profile from CVSS 4.0 · CNA. Fix status from CNA. Impact type from CWE-306.
Summary
TVU Networks Receiver/Transceiver devices running firmware before 7.9 lack authentication on their REST API endpoints. A remote unauthenticated attacker can read sensitive device information and change device configuration, such as DNS settings through a POST request to the LocalNetwork DNS endpoint. Altered DNS settings let an attacker intercept outbound connections to TVU cloud infrastructure, enabling man-in-the-middle attacks. The flaw is classified as CWE-306, Missing Authentication for Critical Function.

Description from the CNA
TVU Networks Receiver/Transceiver devices running firmware before version 7.9 contain a missing authentication vulnerability that allows remote unauthenticated attackers to read sensitive device information and modify device configuration via unprotected REST API endpoints. Attackers can send unauthenticated GET requests to disclose network configuration, firmware details, and cloud service information, or issue POST requests to endpoints such as /Setting3/API/API/v1/LocalNetwork/DNS to alter DNS settings and enable man-in-the-middle attacks on outbound connections to TVU cloud infrastructure.
