EditPlus查找PHP源码简单数字型注入的正则表达式 来源：n3tl04d's Blog 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 ((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select、update 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" 其实自己发现其他的一些漏洞也可以找到相应关键字寻找的，当然这些仅限于比较容易看出来的漏洞了，^_^。 |
