## Technical details

The vulnerability is an unauthenticated remote code execution in the firmware upload functionality (upload.cgi script) affecting SOUND4 IMPACT/FIRST/PULSE/Eco devices running version 2.x and earlier. The vulnerability involves a path traversal flaw that allows attackers to upload malicious files and write them to arbitrary locations on the system with www-data permissions. No authentication is required to exploit this vulnerability, and the attack is network-accessible. Successful exploitation enables full code execution on the affected device.
