Self-registered attackers can enumerate deviceId or serialNumber values to read owner, IP, and location data, and overwrite user_id and tenant_id to take over devices.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-639"],"vendors":[],"products":[],"references":[{"url":"https://github.com/kerwincui/FastBee/blob/v1.2.1/springboot/wumei-iot/src/main/java/com/ruoyi/iot/controller/DeviceController.java#L118-L213","tags":[]},{"url":"https://github.com/kerwincui/FastBee/blob/v2.1.0/springboot/fastbee-open-api/src/main/java/com/fastbee/data/controller/DeviceController.java#L119-L211","tags":[]},{"url":"https://github.com/kerwincui/FastBee/blob/v2.1.0/springboot/fastbee-service/fastbee-iot-service/src/main/java/com/fastbee/iot/service/impl/DeviceServiceImpl.java#L105-L125","tags":[]},{"url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/fastbee-device-ownership-idor","tags":[]},{"url":"https://www.vulncheck.com/advisories/fastbee-through-2.1.0-idor-via-devicecontroller-iot-device-endpoints","tags":[]},{"url":"https://hackmd.io/@1ExmmukzRMWN7B4gQ4W-4Q/fastbee-device-ownership-idor","tags":[]}],"exploitRefs":[{"url":"https://github.com/kerwincui/FastBee/blob/v1.2.1/springboot/wumei-iot/src/main/java/com/ruoyi/iot/controller/DeviceController.java#L118-L213","tags":[]},{"url":"https://github.com/kerwincui/FastBee/blob/v2.1.0/springboot/fastbee-open-api/src/main/java/com/fastbee/data/controller/DeviceController.java#L119-L211","tags":[]},{"url":"https://github.com/kerwincui/FastBee/blob/v2.1.0/springboot/fastbee-service/fastbee-iot-service/src/main/java/com/fastbee/iot/service/impl/DeviceServiceImpl.java#L105-L125","tags":[]}],"hasPoc":true,"ai":null}
