EditPlus查找PHP源码简单数字型注入的正则表达式
今天看一个项目代码，文件不多，不过每个文件中都N多注入，一个一个看实在太累，索性花了点时间，弄了个正则表达式，搜索出来，然后再将安全的筛选出去。省了不少时间的说。1.查找select、update、delete语句<br />
((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 <br />
例子： <br />
select * from user where
2.简单的数字型注入<br />
((select|SELECT|update|UPDATE|delete|DELETE) .*(from|FROM|set|SET) .*(where|WHERE) .*=[ ]?["]?["]?\$)
能找到select、update delete三种语句，5种格式的整形注入，如： <br />
直接变量传入 <br />
select * from guess where id=$subject_id <br />
update guess set is_valid=0 where id=$subject_id <br />
delete from guess where id=$subject_id <br />
=与变量之间存在空格 <br />
select * from guess where id= $subject_id <br />
update guess set is_valid=0 where id= $subject_id <br />
delete from guess where id= $subject_id <br />
变量双引号 <br />
select * from guess where id="$subject_id" <br />
update guess set is_valid=0 where id="$subject_id" <br />
delete from guess where id="$subject_id" <br />
=与双引号之间存在空格 <br />
select * from guess where id= "$subject_id" <br />
update guess set is_valid=0 where id= "$subject_id" <br />
delete from guess where id= "$subject_id" <br />
=与引号、双引号之间存在空格 <br />
select * from guess where id= " $subject_id" <br />
update guess set is_valid=0 where id= " $subject_id" <br />
delete from guess where id= " $subject_id"
<br />
