The Sound4 FIRST web-based management interface is vulnerable to Remote Code Execution (RCE) via a malicious firmware update package. The update mechanism fails to validate the integrity of manual.sh, allowing an attacker to inject arbitrary commands by modifying this script and repackaging the firmware.
