cp -r sqli-labs-php7 /var/www/html/

nginx配置

编辑配置文件 /etc/nginx/sites-enabled/default

# 添加 index.php
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html index.php;

# 取消 php 相关注释，如下
location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        # With php7.0-cgi alone:
        #fastcgi_pass 127.0.0.1:9000;
        # With php7.0-fpm:
        fastcgi_pass unix:/run/php/php7.0-fpm.sock;

关键代码片段如下，传入的ID参数直接构造sql语句，存在注入。

<?php
$sql="SELECT * FROM users WHERE id='$id' LIMIT 0,1";
// $sql="SELECT * FROM users WHERE id='0' union select 1,2,3 -- ' LIMIT 0,1";
// $sql="SELECT * FROM users WHERE id='0' union select 1,2,3 # ' LIMIT 0,1";
$result=mysqli_query($con1, $sql);
$row = mysqli_fetch_array($result, MYSQLI_BOTH);

?>
