Detailsinfo

A vulnerability, which was classified as problematic, has been found in Tomofun Furbo 360 and Furbo Mini (Firmware Software) (the affected version is unknown). Affected by this issue is an unknown code of the component Trial Restriction Handler. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. Impacted is confidentiality, integrity, and availability.

The bug was discovered 05/15/2025. The weakness was disclosed by Calvin Star, Julian B (skelet4r and dead1nfluence) with Software Secured. This vulnerability allows an attacker with physical access to the device to bypass trial restrictions by modifying the device's MAC address. Each time the MAC address on the device is changed a new corresponding DeviceID is assigned to the Furbo which results in a fresh 30-day premium trial being assigned to the device during the registration process. This effectively grants unlimited access to premium features for the Furbo device. This vulnerability is handled as CVE-2025-11641. The exploitation is known to be difficult. The attack needs to be approached locally. No form of authentication is required for exploitation. Technical details are unknown but a private exploit is available. The MITRE ATT&CK project declares the attack technique as T1068.

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. Change the MAC address specified within the factory.json file 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

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-2025-33905). Once again VulDB remains the best source for vulnerability data.
