Technical details

An OS command injection vulnerability exists in the ioos binary's sub_23B54 function, which concatenates an unsanitized file_id parameter from /protocol.csp?opt=ovpn_file requests (with type=del) into a shell command passed to popen(). The vulnerability is unauthenticated because the ioos binary trusts the IP-FROM HTTP header to determine if requests originate from localhost, allowing an attacker to forge this header to bypass login checks. No credentials or user interaction are required; network access alone is sufficient for exploitation.
