SQL注入概述

什么是SQL注入？

SQL注入是一种常见的网络攻击手段，攻击者通过在输入数据中插入恶意的SQL代码，从而获取数据库的访问权限或执行非法操作。

SQL注入的危害

  • 窃取敏感数据：如用户名、密码、身份证号等。
  • 修改数据：篡改、删除或添加数据。
  • 控制服务器：执行系统命令，控制服务器。

SQLmap实战案例

案例一：检测登录页面SQL注入漏洞

  1. 检测URL：http://example.com/login.php?username=admin&password=123456
  2. 执行命令：
python sqlmap.py -u "http://example.com/login.php?username=admin&password=123456" -p "username"
  1. 结果：
