CVE-2025-63215 identifies a remote code execution vulnerability in the Sound4 IMPACT device's web-based management interface. The root cause is the failure of the firmware update mechanism to validate the integrity of the manual.sh script included in firmware update packages. An attacker with high privileges can craft a malicious firmware update by modifying manual.sh to include arbitrary commands. When the device processes this update, it executes the injected commands, resulting in remote code execution. This vulnerability falls under CWE-494 (Download of Code Without Integrity Check), indicating a lack of proper verification of code authenticity. The CVSS v3.1 base score is 7.2, reflecting a high severity due to network attack vector, low attack complexity, required privileges, and impact on confidentiality, integrity, and availability. No patches or exploits are currently publicly available, but the vulnerability poses a significant risk to affected devices. The absence of user interaction simplifies exploitation once privileges are obtained. The vulnerability could be leveraged to gain persistent control over the device, disrupt operations, or pivot within a network.

For European organizations, especially those in sectors such as telecommunications, energy, and critical infrastructure that may deploy Sound4 IMPACT devices, this vulnerability presents a serious risk. Successful exploitation could lead to unauthorized control over network management interfaces, enabling attackers to disrupt services, exfiltrate sensitive data, or launch further attacks within the network. The compromise of management interfaces can undermine network integrity and availability, potentially causing operational outages or safety issues. Given the high confidentiality, integrity, and availability impacts, organizations could face regulatory penalties under GDPR if personal data is compromised. The lack of known exploits currently provides a window for proactive mitigation, but the risk of future exploitation remains significant.

Organizations should implement strict controls around firmware update processes, including enforcing cryptographic signature verification for all firmware packages to ensure integrity and authenticity. Access to the firmware update functionality should be restricted to trusted administrators with multi-factor authentication and minimal necessary privileges. Network segmentation should isolate management interfaces from general network access to reduce exposure. Continuous monitoring and logging of firmware update activities can help detect unauthorized attempts. Vendors should be engaged to provide patches or updated firmware that includes integrity checks for manual.sh and other critical scripts. Until patches are available, organizations might consider disabling manual firmware updates or using alternative secure update mechanisms. Regular security audits and penetration testing focusing on device management interfaces are recommended to identify and remediate similar issues.
