CVE-2026-104076

Status: DeferredCritical (9.3)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vulnerabilidad de autenticación faltante en API REST remota sin privilegios (AV:N/PR:N) permite lectura de información sensible (VC:H) y modificación de configuración de DNS para ataques MitM.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
