Description
The issue concerns a lack of proper access control when executing actions on Nexx Smart Home devices. An attacker with a valid
deviceId could exploit this to retrieve device history, set device settings, and retrieve device information. The vulnerability is related to bypassing authorization using a user-controlled key, allowing a remote attacker to modify device settings and obtain device information.Recommendations
For Nexx Smart Home devices, consider restricting access to device settings and information until a patch is available.
For Nexx Garage Door Controller (NXG-100B, NXG-200), Nexx Smart Plug (NXPG-100W), and Nexx Smart Alarm (NXAL-100), restrict access to the devices to minimize the risk of exploitation.
As a temporary workaround, consider disabling the use of user-controlled keys to prevent authorization bypass.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
