Overview
CVE-2025-63215 identifies a critical Remote Code Execution (RCE) vulnerability found in the web-based management interface of Sound4 IMPACT devices. This flaw allows a remote attacker to execute arbitrary code on the device by exploiting a weakness in the firmware update mechanism. The vulnerability stems from the insufficient validation of the integrity of the `manual.sh` script during the firmware update process.
Technical Details
The Sound4 IMPACT firmware update process, when performed manually, lacks sufficient validation of the files included in the update package. Specifically, the `manual.sh` script, intended for performing specific configuration tasks during the update, is not adequately checked for malicious content. An attacker can exploit this by:
- Modifying the `manual.sh` script to include arbitrary commands.
- Repackaging the modified script into a malicious firmware update package.
- Uploading the malicious package through the web-based management interface.
Upon installation of the malicious package, the attacker’s commands embedded within `manual.sh` will be executed with the privileges of the user running the update process, leading to Remote Code Execution.
CVSS Analysis
As of the publication date (2025-11-18), a CVSS score is not yet available. However, given the potential for Remote Code Execution, the severity is expected to be rated as Critical, likely with a CVSS score in the range of 9.0-10.0. Awaiting NVD analysis.
Possible Impact
Successful exploitation of CVE-2025-63215 can have severe consequences, including:
- Complete compromise of the Sound4 IMPACT device.
- Data exfiltration and theft of sensitive information.
- Installation of malware or backdoors for persistent access.
- Disruption of audio processing and broadcast operations.
- Potential lateral movement to other devices on the network.
Mitigation or Patch Steps
To mitigate the risk posed by CVE-2025-63215, the following steps are recommended:
- Apply the official patch: Sound4 has been notified and a patch is expected. Visit Sound4’s Helpdesk website and download page to obtain and install the latest firmware update as soon as it becomes available.
- Restrict access: Limit access to the web-based management interface to authorized personnel only.
- Monitor network traffic: Monitor network traffic for any suspicious activity originating from Sound4 IMPACT devices.
- Implement network segmentation: Isolate Sound4 IMPACT devices on a separate network segment to limit the potential impact of a successful attack.
