Technical details
The /ap_ip.cgi CGI handler processes the "ip" parameter via strncpy without validation and passes it unsanitized to a system() call within a shell command. The vulnerability is reachable without authentication due to a .ico whitelist bypass. An attacker must know or guess a MAC address of a bound access point; exploitation is limited to ~19-byte payloads on this endpoint due to buffer truncation, though longer commands can be chained across multiple requests.
