CVE-2025-65824 is a vulnerability in Meatmeet devices that enables an unauthenticated attacker within Bluetooth Low Energy (BLE) range to perform unauthorized Over The Air (OTA) firmware upgrades. The core issue stems from the device's failure to authenticate or verify the integrity of firmware updates, violating secure update principles and allowing arbitrary code to be flashed onto the device. This lack of validation means an attacker can overwrite the legitimate firmware with malicious code, resulting in remote code execution (RCE) on the device. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function) and carries a CVSS v3.1 score of 8.8, indicating high severity. The attack vector requires proximity (BLE range), no privileges or user interaction, and impacts confidentiality, integrity, and availability fully. The compromised device becomes completely controlled by the attacker, potentially enabling further lateral movement or disruption. No patches or mitigations have been officially released yet, and no exploits are known in the wild as of the publication date. The vulnerability highlights critical security design flaws in the OTA update mechanism of Meatmeet devices, emphasizing the need for cryptographic verification and authentication in firmware updates.

For European organizations, this vulnerability presents a significant risk especially in sectors where Meatmeet devices are deployed for operational or security purposes. The ability for an attacker to remotely execute code and fully control the device can lead to data breaches, operational disruption, and loss of service availability. Critical infrastructure, healthcare, manufacturing, and logistics sectors using these devices could face severe operational impacts. The proximity requirement limits remote exploitation but does not eliminate risk in environments with physical access by unauthorized personnel or adversaries. Additionally, compromised devices could serve as footholds for broader network intrusion or espionage. The lack of authentication in firmware updates undermines trust in device integrity, potentially leading to regulatory and compliance issues under European data protection and cybersecurity laws. Organizations may also face reputational damage and financial losses if devices are exploited in attacks.

1. Immediately restrict physical access to Meatmeet devices, especially in public or unsecured areas, to prevent attackers from coming within BLE range. 2. Disable OTA firmware updates via BLE if the device configuration allows, or restrict update functionality to trusted personnel and secure environments. 3. Monitor BLE traffic for unusual or unauthorized firmware update attempts using specialized BLE security monitoring tools. 4. Implement network segmentation to isolate Meatmeet devices from critical systems to limit lateral movement if compromised. 5. Engage with the vendor for firmware updates or patches that implement proper authentication and integrity checks on OTA updates; prioritize deployment once available. 6. Consider deploying BLE signal jamming or shielding in highly sensitive environments to reduce attack surface. 7. Conduct regular security audits and penetration tests focusing on wireless interfaces and update mechanisms. 8. Educate staff about the risks of physical proximity attacks and enforce strict access controls around device locations.
