CVE-2025-11633 identifies a security vulnerability in Tomofun's Furbo 360 and Furbo Mini pet cameras, specifically within the HTTP Traffic Handler component. The vulnerability arises from improper certificate validation in the upload_file_to_s3 function of the collect_logs.sh script. This flaw could allow a remote attacker to interfere with the device's HTTPS communication, potentially enabling man-in-the-middle (MITM) attacks or unauthorized data interception during log uploads to Amazon S3 storage. The vulnerability affects firmware versions up to FB0035_FW_036 for Furbo 360 and MC0020_FW_074 for Furbo Mini. Exploitation is considered highly complex, requiring advanced skills and conditions, and no public exploits are currently known. The vulnerability does not require authentication or user interaction, but the impact on confidentiality is limited, and integrity and availability impacts are minimal. The vendor was contacted early but has not responded or issued patches, leaving affected devices exposed. The CVSS 4.0 base score is 6.3 (medium severity), reflecting network attack vector, high attack complexity, and no privileges or user interaction needed. This vulnerability highlights risks in IoT device firmware, especially in certificate validation mechanisms critical for secure communications.

For European organizations, the impact of CVE-2025-11633 primarily concerns privacy and data security related to IoT devices used in homes or offices. While the vulnerability does not directly compromise core enterprise systems, exploitation could lead to interception or manipulation of data transmitted by Furbo devices, potentially exposing sensitive information or enabling further attacks within a local network. Organizations deploying these devices in sensitive environments may face increased risk of unauthorized surveillance or data leakage. The lack of vendor response and patches prolongs exposure, increasing the window for potential exploitation. However, the high complexity of attack and absence of known exploits reduce immediate risk. Still, the presence of vulnerable IoT devices can serve as a foothold for attackers targeting broader network infrastructure, especially in environments with weak segmentation or monitoring. European privacy regulations such as GDPR may also be implicated if personal data is compromised through these devices.

European organizations and individual users should take proactive steps to mitigate this vulnerability: 1) Immediately inventory and identify all Furbo 360 and Furbo Mini devices running affected firmware versions (up to FB0035_FW_036 and MC0020_FW_074). 2) Restrict network access to these devices by isolating them on segmented VLANs or dedicated IoT networks to limit exposure to untrusted networks. 3) Monitor network traffic for unusual HTTPS connections or anomalies related to the devices’ log upload processes. 4) Disable or limit remote access features where possible to reduce attack surface. 5) Regularly check for firmware updates or security advisories from Tomofun, and apply patches promptly once available. 6) Consider replacing devices with more secure alternatives if vendor support remains absent. 7) Employ network-level protections such as TLS interception detection and certificate pinning where feasible to detect improper certificate validation attempts. 8) Educate users about the risks of IoT devices and enforce strict policies on their deployment in sensitive environments.
