Detailsinfo

A vulnerability, which was classified as problematic, was found in Tomofun Furbo 360 and Furbo Mini (Firmware Software) (unknown version). This affects an unknown code block of the component Registration Handler. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability.

The bug was discovered 05/15/2025. The weakness was presented by Calvin Star, Julian B (skelet4r and dead1nfluence) with Software Secured. An attacker with physical access to a Furbo device can spoof the DeviceID of a victim’s unregistered device and complete the registration process for that DeviceID. Once the registration process is completed the Victim's DeviceID is bound to the Attackers Account. This results in a denial of service for the victim as they are then unable to register or use the device associated with that DeviceID. This vulnerability is uniquely identified as CVE-2025-11642. The exploitability is told to be difficult. An attack has to be approached locally. Technical details are unknown but a private exploit is available.

A private exploit has been developed by Calvin Star (Skelet4r) in Bash. 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. Replication Steps: 1. Modify the factory config file located in /mnt/hw/factory.json to include the MAC address and BTMAC address 2. Replace the MAC address specified within the factory.json file with the Victim's MAC Address 3. Remove the device configuration file located in /mnt/flash/furbo/setup_info.json 4. Reboot the Furbo 5. Complete the registration process of the Furbo in the mobile app 6. Observe the Victim DeviceID associated with your account

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-2025-33907). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
