A vulnerability classified as critical has been found in myStrom WiFi Switch, WiFi Switch EU, WiFi Bulb, WiFi LED Strip, WiFi Button and WiFi Button Plus (Wireless LAN Software). Affected is some unknown functionality. The manipulation as part of a MAC Address leads to a access control vulnerability. CWE is classifying the issue as CWE-264. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An issue was discovered in myStrom WiFi Switch V1 before 2.66, WiFi Switch V2 before 3.80, WiFi Switch EU before 3.80, WiFi Bulb before 2.58, WiFi LED Strip before 3.80, WiFi Button before 2.73, and WiFi Button Plus before 2.73. The process of registering a device with a cloud account was based on an activation code derived from the device MAC address. By guessing valid MAC addresses or using MAC addresses printed on devices in shops and reverse engineering the protocol, an attacker would have been able to register previously unregistered devices to their account. When the rightful owner would have connected them after purchase to their WiFi network, the devices would not have registered with their account, would subsequently not have been controllable from the owner's mobile app, and would not have been visible in the owner's account. Instead, they would have been under control of the attacker.

The bug was discovered 08/29/2018. The weakness was released 08/30/2018 (Website). The advisory is available at swisscom.ch. This vulnerability is traded as CVE-2018-15478 since 08/17/2018. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.
