Make your neighbor think their house is haunted by blinking their Ikea smart bulbs
A couple of vulnerabilities in Ikea smart lighting systems can be exploited to make lights annoyingly flicker for hours.hope to exploit to steal government secrets or wreak havoc on high-value targets, the vulnerabilities could provide some mildly disruptive entertainment for, say, an annoying next-door neighbor looking for some spooky-month hi-jinx.
In a couple write-ups about the bugs, the researchers described how CVE-2022-39064, the vulnerability in the Tradfri smart bulbs, could be exploited by sending a single malformed Zigbee frame over the air that makes the light blink. Resending the frame multiple times forces the bulb to perform a factory reset, which erases its configuration and other information, such as brightness level.
"To recover from this attack, a user could add each bulb manually back to the network," according to the alert."However, an attacker could reproduce the attack at any time.", that affects the Ikea Tradfri smart lighting gateway, which controls the lights. Similar to the bulb bug, a malformed Zigbee frame renders the gateway unresponsive so that it can't control the connected lights and other devices via the Ikea Home Smart app.
