# Hisense VIDAA smart TV: LAN attacker can change volume and reset settings

Link for people: https://infrastack.ai/live/CVE-2026-123996 (this .md is for agents)

Hisense VIDAA smart TV firmware V0000.01.00a.P0220 exposes its UPnP/DLNA RenderingControl service on TCP port 38400 without per-command authentication after a one-time pairing. A device on the same local network can change volume and mute, and reset picture and audio calibration.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains a missing authentication vulnerability in the UPnP/DLNA RenderingControl service on TCP port 38400 that allows a LAN-adjacent attacker to issue SetVolume, SetMute, and SelectPreset(FactoryDefaults) commands after a one-time DLNA pairing with no per-command authentication or session token. Attackers can send a continuous loop of unauthenticated commands to override the physical remote, change volume and mute, and reset all picture and audio calibration settings.
