CVE-2018-15480 is a high-severity vulnerability affecting various myStrom WiFi devices, including Switches, Bulbs, LED Strips, and Buttons, across multiple firmware versions. It involves a hidden cloud API parameter that, when combined with an insecure device registration, allows an authenticated attacker to redirect a registered device to a rogue API server. This enables the attacker to issue arbitrary commands, including firmware updates, to the compromised device. The vulnerability has a CVSSv3 score of 8.8 (High), indicating a network-based attack with low complexity, requiring only low privileges, and leading to high confidentiality, integrity, and availability impacts. Despite its severity, there is no evidence of active exploitation, nor are there publicly available exploit modules or significant community discussion surrounding this CVE.
