Detailsinfo

A vulnerability was found in Tomofun Furbo 360 and Furbo Mini (Firmware Software) (the affected version unknown). It has been rated as problematic. Affected by this issue is an unknown part of the component GATT Service. The manipulation of the argument DeviceToken with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality.

The bug was discovered 05/15/2025. The weakness was presented by Calvin Star, Julian B (skelet4r and dead1nfluence) with Software Secured. The advisory is available at github.com. An attacker within Bluetooth Low Energy (BLE) range of the Furbo Mini device can read a GATT characteristic that leaks the device’s DeviceToken. This token is used to authenticate the device with Furbo’s backend services. If intercepted, an attacker can reuse the DeviceToken to re-register the victim’s device to a rogue account, effectively disabling the victim’s access and ability to use their device. This vulnerability is handled as CVE-2025-11647. The exploitation is known to be difficult. The attack needs to be done within the local network. No form of authentication is required for exploitation. Technical details as well as a private exploit are known. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.

A private exploit has been developed by Calvin Star (Skelet4r). The exploit is available at github.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 149 days. During that time the estimated underground price was around . The vendor was contacted early about this disclosure but did not respond in any way. The firmware versions determined to be affected are Furbo 360 up to FB0035_FW_036 and Furbo Mini up to MC0020_FW_074. Exploitation: 1. Launch the Furbo_Master.py script. 2. Scan and connect to the Furbo device shown in the BLE device list. 3. Execute the reset command to trigger BLE reinitialization. 4. Execute the reconnect command to resume communication. 5. Scan again and reconnect to the re-advertised Furbo device. 6. Execute the read_device_token command. 7. Observe the returned Device Token from the BLE characteristic.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-33911). If you want to get best quality of vulnerability data, you may have to visit VulDB.
