Detailsinfo

A vulnerability, which was 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 by this issue is an unknown code of the component Device Registration. The manipulation as part of a Parameter leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is 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 cloud API had a hidden parameter, which allowed an authenticated user to reconfigure the server URL for a device registered to their account. In combination with an insecure device registration vulnerability, this allowed an attacker to reconfigure a maliciously registered device to their own rogue replica of the myStrom API and issue commands to the device, including firmware update commands.

The bug was discovered 08/29/2018. The weakness was presented 08/30/2018 (Website). The advisory is shared for download at swisscom.ch. This vulnerability is handled as CVE-2018-15480 since 08/17/2018. The exploitation is known to be easy. The attack may be launched remotely. A simple authentication is needed for exploitation.
