EditPlus查找PHP源码简单数字型注入的正则

饭哥的文章
1.查找selectupdatedelete语句
((select|SELECT|update|UPDATE|delete|DELETE)+.*(from|FROM|set|SET)+.*(where|WHERE)+.*)

查询语句,对于没有条件判断的基本不存在注入问题,因而仅搜索此语句即可
例子:
select * from user where

2.简单的数字型注入
((select|SELECT|update|UPDATE|delete|DELETE)+.*(from|FROM|set|SET)+.*(where|WHERE)+.*=[ ]?["]?["]?\$)

能找到selectupdate delete三种语句,5种格式的整形注入,如:
直接变量传入
select * from guess where id=$subject_id
update guess set is_valid=0 where id=$subject_id
delete from guess where id=$subject_id
=与变量之间存在空格
select * from guess where id= $subject_id
update guess set is_valid=0 where id= $subject_id
delete from guess where id= $subject_id
变量双引号
select * from guess where id="$subject_id"
update guess set is_valid=0 where id="$subject_id"
delete from guess where id="$subject_id"
=与双引号之间存在空格
select * from guess where id= "$subject_id"
update guess set is_valid=0 where id= "$subject_id"
delete from guess where id= "$subject_id"
=与引号、双引号之间存在空格
select * from guess where id= " $subject_id"
update guess set is_valid=0 where id= " $subject_id"
delete from guess where id= " $subject_id"
