The binary reads the \"imei\" parameter from a web request and verifies only that it is 15 characters long. The parameter is then directly inserted into a system command using sprintf() and executed with system(). Maliciously crafted IMEI input can execute arbitrary commands on the router without authentication."

El binario lee el parámetro ’imei’ de una solicitud web y verifica únicamente que tenga 15 caracteres de longitud. El parámetro es luego insertado directamente en un comando del sistema usando sprintf() y ejecutado con system(). Una entrada IMEI maliciosamente elaborada puede ejecutar comandos arbitrarios en el router sin autenticación."
