CVE-2018-15478
8.1 · HIGHOverview
CVE-2018-15478 is a high-severity vulnerability affecting mystrom wifi_switch_firmware. It was published on August 30, 2018 and has a CVSS 3.0 base score of 8.1 (HIGH).
This vulnerability has a CVSS 3.0 base score of 8.1, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from mystrom. Update wifi_switch_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
