Researchers have demonstrated how an attacker could take over control of light bulbs in the Ikea Trådfri smart lighting system, ultimately turning the bulbs up to full brightness — and users can’t turn them down through the app or the remote control.
Cybersecurity analysts at Synopsys CyRC found that if a threat actor re-sent the same malformed Zigbee frame (IEEE 802.15.4) over and over again, an attacker could advantage of two vulnerabilities (tracked under CVE-2022-39064 and CVE-2022-39065) in the Ikea Trådfri smart lighting system.
