CVE-2025-9576 is a vulnerability identified in the seeedstudio ReSpeaker LinkIt7688 device, specifically related to the administrative interface's handling of credentials stored or referenced in the /etc/shadow file. The vulnerability arises from the use of default credentials, which can be exploited by an attacker with local access to the device. The attack complexity is high, indicating that exploitation requires significant effort or specialized knowledge. The vulnerability does not require user interaction and does not allow remote exploitation, as the attack vector is local (AV:L). The exploitability is considered difficult (AC:H), and the attacker must have low privileges (PR:L) to attempt exploitation. The vulnerability impacts confidentiality to a low degree, with no direct impact on integrity or availability. The vendor was notified but did not respond, and no patches or mitigations have been published yet. Although an exploit is publicly available, there are no known exploits in the wild at this time. The CVSS 4.0 base score is 2, reflecting a low severity level. The vulnerability could allow an attacker with local access to gain unauthorized administrative access by leveraging default credentials, potentially leading to unauthorized configuration changes or information disclosure within the device.

For European organizations, the impact of CVE-2025-9576 is limited primarily to environments where seeedstudio ReSpeaker LinkIt7688 devices are deployed and where local access to these devices is feasible. Given the requirement for local access and the high complexity of exploitation, the risk is relatively low in typical enterprise environments with proper physical security controls. However, in scenarios such as research labs, IoT development environments, or edge deployments where these devices are used and physical or local network access is possible, the vulnerability could be exploited to gain unauthorized administrative control. This could lead to unauthorized configuration changes, potential data leakage, or pivoting to other internal systems if the device is part of a larger network. The lack of vendor response and absence of patches increases the risk of exploitation over time. Organizations relying on these devices for voice or IoT applications should be aware of the potential for local privilege escalation or unauthorized access, which could undermine device integrity and confidentiality.

1. Physically secure all seeedstudio ReSpeaker LinkIt7688 devices to prevent unauthorized local access. 2. Change all default credentials immediately upon deployment or discovery of the device in the network. 3. Implement network segmentation to isolate these devices from critical infrastructure and sensitive data networks, limiting the impact of any compromise. 4. Monitor local access logs and device usage for unusual activity that might indicate exploitation attempts. 5. If possible, disable or restrict administrative interfaces that are not required or expose default credentials. 6. Engage with seeedstudio or community forums for any unofficial patches or workarounds until an official fix is released. 7. Consider replacing affected devices with alternatives that do not have this vulnerability if physical security or credential management cannot be guaranteed. 8. Conduct regular security audits and penetration tests focusing on IoT and edge devices to identify similar vulnerabilities.
