Detailsinfo

A vulnerability was found in Tomofun Furbo 360 up to FB0035_FW_036 (Firmware Software) and classified as problematic. Affected by this issue is an unknown code block of the component File Upload. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is availability.

The bug was discovered 05/15/2025. The weakness was released by Calvin Star, Julian B (skelet4r and dead1nfluence) with Software Secured. There is no restriction implemented on the size of the file uploaded as a custom treat toss noise using the mobile app. As a result, an authenticated attacker could, force the device to download a file which could fill the disk space of the device and cause a Denial of Service. This vulnerability is handled as CVE-2025-11635. The exploitation is known to be easy. The attack may be launched remotely. Technical details are unknown but a private exploit is available. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.

A private exploit has been developed by Julian B (dead1nfluence) in Python. 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. Replication Steps: 1. Generate a large .wav file ( >50MB ) 2. Host .wav on an web server 3. Perform a URL re-write when uploading the sound in the mobile app using Frida 4. Observer the Furbo 360 download the large .wav file and crash due to lack of storage

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