Detailsinfo

A vulnerability was found in Tomofun Furbo 360 up to FB0035_FW_036 (Firmware Software). It has been classified as critical. This affects some unknown processing of the component Account Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on 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. An attacker who compromises the Furbo account of a legitimate user can coerce the device to make a request to an attacker-controlled server by modifying the URL which is sent during the recording of a new treat toss sound. The end result is that the Furbo will download a file from the attacker's server. This vulnerability is uniquely identified as CVE-2025-11636. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a private exploit is available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 10/31/2025).

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. 1. Create a Frida script hook the treat toss service and replace the URL with an attacker controlled URL 2. Start the Furbo app and Frida Server on a jail broken phone 3. Run the Fride Script 4. In the Furbo app, navigate to the Furbo device settings. 5. Select Treat Toss Sound and enable "Record My Own Sound". 6. Record a short audio clip and Swipe right to push the change. 7. On the attacker-controlled server, observe the inbound request from the Furbo Device.

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-2025-33899). Be aware that VulDB is the high quality source for vulnerability data.
