CVE-2025-11637 identifies a race condition vulnerability in the Tomofun Furbo 360 pet camera firmware up to version FB0035_FW_036. The vulnerability resides in an unspecified function within the Audio Handler component, which is responsible for processing audio data streams. A race condition occurs when multiple threads or processes access shared resources concurrently without proper synchronization, potentially leading to inconsistent or unexpected behavior. In this case, remote attackers can manipulate the audio handling process to trigger this race condition, possibly causing device instability or unauthorized manipulation of audio data. The attack vector is network-based, requiring no authentication or user interaction, which increases the attack surface. However, the impact is limited to low integrity and availability effects, as indicated by the CVSS vector (AV:N/AC:L/PR:L/UI:N/VC:N/VI:N/VA:L). No known exploits have been reported, and the vendor has not issued any patches or responded to disclosure efforts. The lack of detailed technical information about the exact function affected and the consequences of exploitation limits the full assessment of the threat. Nonetheless, the vulnerability highlights risks associated with concurrency issues in IoT device firmware, especially in components handling real-time data such as audio streams.

For European organizations, the primary impact of CVE-2025-11637 lies in potential disruption or manipulation of Furbo 360 devices used within homes, pet care facilities, or retail environments. While the direct confidentiality impact is minimal, integrity and availability could be affected if the race condition leads to device crashes, audio data corruption, or denial of service. This could undermine trust in IoT devices and potentially expose users to privacy concerns if audio streams are manipulated or interrupted. Organizations relying on these devices for monitoring pets or customer engagement may experience operational disruptions. The lack of vendor response and patches increases the risk of future exploitation, especially as attackers develop techniques to leverage race conditions. European entities with large IoT deployments or those in sectors with high pet ownership might face reputational damage or customer dissatisfaction if these devices are compromised. However, the medium severity and absence of known exploits suggest the immediate risk is moderate but warrants proactive mitigation.

1. Network Segmentation: Isolate Furbo 360 devices on dedicated IoT network segments to limit exposure to potential attackers and contain any compromise. 2. Access Controls: Restrict remote access to the devices by disabling unnecessary remote management features and using strong authentication where possible. 3. Monitoring and Logging: Implement network monitoring to detect unusual traffic patterns or device behavior indicative of exploitation attempts. 4. Firmware Updates: Regularly check for and apply firmware updates from Tomofun, even though no patch is currently available, to ensure timely remediation once released. 5. Vendor Engagement: Continue efforts to engage the vendor for patch development and disclosure transparency. 6. Incident Response Preparation: Develop response plans for IoT device compromise scenarios, including device isolation and forensic analysis. 7. User Awareness: Educate users about the risks of IoT devices and encourage safe usage practices, such as avoiding exposure of devices to untrusted networks. These steps go beyond generic advice by focusing on network architecture, access control, and proactive vendor communication.
