CVE-2025-11642 identifies a denial of service vulnerability in Tomofun's Furbo 360 and Furbo Mini pet cameras, specifically within an unspecified function of the Registration Handler component. The vulnerability allows an attacker with physical access to the device to manipulate it in a way that causes a denial of service, rendering the device non-functional or unresponsive. The attack complexity is high, and exploitation is difficult, requiring no user interaction or authentication but physical proximity to the device. The affected firmware versions are Furbo 360 up to FB0035_FW_036 and Furbo Mini up to MC0020_FW_074. The vendor was notified early but has not issued any response or patches. The CVSS 4.1 score reflects medium severity, with attack vector being physical, high attack complexity, and no privileges or user interaction required. The vulnerability impacts device availability but does not affect confidentiality or integrity. No known exploits have been reported in the wild, limiting immediate risk. However, the lack of vendor response and patch availability means affected devices remain vulnerable. The Registration Handler likely manages device registration or pairing processes, and manipulation here could disrupt normal device operation. This vulnerability highlights risks in IoT devices where physical access can lead to service disruption, emphasizing the need for physical security and firmware update mechanisms.

For European organizations, the primary impact of CVE-2025-11642 is operational disruption due to denial of service on Furbo 360 and Furbo Mini devices. While these devices are primarily consumer pet cameras, some organizations may use them for monitoring or security purposes in office or home environments. A successful attack could cause loss of video monitoring capability, potentially impacting security or surveillance functions. The physical access requirement limits remote exploitation risk but raises concerns in shared or public spaces where devices may be accessible. The medium severity and lack of confidentiality or integrity impact reduce the risk of data breaches but do not eliminate operational risks. The absence of vendor patches prolongs exposure and complicates remediation. European organizations with extensive IoT deployments or reliance on these devices should consider the risk of service interruption and potential cascading effects on security monitoring or pet care services. Additionally, reputational damage could occur if service outages affect customer-facing environments. Overall, the impact is moderate but non-negligible, especially in environments where device availability is critical.

1. Enforce strict physical security controls to prevent unauthorized access to Furbo 360 and Furbo Mini devices, including placement in secure or monitored locations. 2. Monitor devices for signs of malfunction or unavailability that could indicate exploitation attempts. 3. Limit the number of personnel with physical access to these devices and maintain access logs where possible. 4. Segregate IoT devices on dedicated network segments to reduce potential lateral impact if devices become non-functional. 5. Regularly check for vendor updates or firmware patches addressing this vulnerability, and apply them promptly once available. 6. Consider disabling or restricting the Registration Handler functionality if configurable, or isolate the device from critical systems. 7. Implement incident response plans that include procedures for IoT device failures to minimize operational disruption. 8. Evaluate alternative devices with better security track records if Furbo devices are critical to operations. 9. Educate staff about the risks of physical tampering with IoT devices and encourage reporting of suspicious activity. 10. Engage with the vendor or community to advocate for vulnerability remediation and transparency.
