## Overview

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.

## Affected

- `VIDAA 0000.01.00a.P0220`
