A flaw has been found in Tomofun Furbo 360 and Furbo Mini. This issue affects some unknown processing of the component GATT Service. This manipulation of the argument DeviceToken causes information disclosure. The attack is only possible within the local network. A high degree of complexity is needed for the attack. The exploitability is assessed as difficult. The firmware versions determined to be affected are Furbo 360 up to FB0035_FW_036 and Furbo Mini up to MC0020_FW_074. The vendor was contacted early about this disclosure but did not respond in any way.

The simplepush server iterates through the application installations and pushes a notification to the server provided by deviceToken. But this is user controlled. If a bogus applications is registered with bad deviceTokens, one can generate endless exceptions when those endpoints can't be reached or can slow the server down by purposefully wasting it's time with slow endpoints. Similarly, one can provide whatever HTTP end point they want. This turns the server into a DDOS vector or an anonymizer for the posting of malware and so on.
