Technical details

The UPnP/DLNA RenderingControl service on TCP port 38400 implements no per-command authentication or session validation after an initial DLNA pairing, allowing any network-adjacent attacker to invoke SetVolume, SetMute, and SelectPreset(FactoryDefaults) SOAP commands. An attacker can send repeated commands to continuously override the physical remote and reset calibration settings. A fix has not been announced.
