CVE-2025-2818 is a medium-severity vulnerability identified in version 1.0 of the Bluetooth Transmission Alliance protocol as implemented by the Motorola Smart Connect Android Application. The vulnerability stems from the cleartext transmission of sensitive information during file transfers to devices that are not paired within the Smart Connect ecosystem. Specifically, when a user transfers files via Bluetooth to an unpaired device, the data is transmitted without encryption, allowing any attacker within Bluetooth range to intercept and potentially capture these files. This vulnerability is classified under CWE-319, which pertains to the cleartext transmission of sensitive information. The attack vector is adjacent (AV:A), meaning the attacker must be within Bluetooth range, which typically spans up to 10 meters for classic Bluetooth. The vulnerability does not require privileges or authentication, but does require user interaction (UI:P), such as initiating a file transfer. The impact on confidentiality is low to moderate since only unpaired device transfers are affected, and the integrity and availability of the system are not impacted. No known exploits are currently reported in the wild, and no patches have been released yet. The vulnerability affects the Motorola Smart Connect Android Application, which is used to manage Bluetooth connections and file transfers on Motorola devices. The CVSS 4.0 vector indicates no scope change, no privilege requirements, and no impact on integrity or availability, but a partial impact on confidentiality due to data interception risk.

For European organizations, the primary impact of this vulnerability lies in the potential interception of sensitive files transmitted via Bluetooth to unpaired devices using Motorola smartphones with the affected Smart Connect app version. This could lead to unauthorized disclosure of confidential corporate data, intellectual property, or personally identifiable information if employees use affected devices for file transfers in proximity to malicious actors. The risk is heightened in environments where Bluetooth is commonly used for quick file sharing, such as offices, conference centers, or public spaces. However, the attack requires physical proximity and user initiation of file transfers to unpaired devices, limiting the attack surface. The vulnerability does not affect paired device communications, which are typically encrypted. The lack of known exploits reduces immediate risk, but the presence of this vulnerability could be leveraged in targeted espionage or data theft campaigns. Organizations handling sensitive data or operating in regulated sectors (finance, healthcare, government) should be particularly cautious. Additionally, the vulnerability could undermine trust in Motorola devices within enterprise environments, potentially impacting device management and security policies.

To mitigate this vulnerability effectively, European organizations should implement the following specific measures: 1) Restrict or disable Bluetooth file transfers to unpaired devices on Motorola smartphones, especially in sensitive or high-risk environments. This can be enforced via mobile device management (MDM) policies that control Bluetooth usage and app permissions. 2) Educate users about the risks of transferring files to unpaired devices and encourage the use of secure, encrypted file-sharing methods instead of Bluetooth for sensitive data. 3) Monitor Bluetooth activity logs on managed devices to detect unusual or unauthorized file transfer attempts. 4) Coordinate with Motorola and Lenovo to obtain updates or patches addressing this vulnerability as soon as they become available and prioritize their deployment. 5) Where possible, enforce the use of paired device transfers only, as these are not affected by the vulnerability. 6) Consider disabling Bluetooth entirely on devices that do not require it for business operations to reduce the attack surface. 7) Implement network segmentation and endpoint security controls to limit lateral movement and data exfiltration in case of compromise. These targeted mitigations go beyond generic advice by focusing on controlling Bluetooth usage and user behavior specific to the vulnerability context.
