| Título | Wavlink WL-WN530BE1-A M30BE1_V251117 CWE-306 |
|---|
| Descrição | This vulnerability resides in sub_23B54. When the ioos binary processes requests to /protocol.csp?opt=ovpn_file, the sub_23B54 function concatenates the user-controlled file_id parameter into a shell command string via snprintf() without any sanitization, and subsequently passes it to popen() for execution.The ioos binary extracts the IP-FROM field from the HTTP request header and assigns it to con->ip_from. The con_check_read_finish function then evaluates whether con->ip_from equals "127.0.0.1" to decide whether to skip the login verification process. However, because con->ip_from originates from a client-supplied HTTP header rather than the actual TCP socket peer address, an attacker can trivially forge IP-FROM: 127.0.0.1 to bypass all authentication checks without any credentials. |
