SQL注入过滤绕过fuzz字典

news 2025/10/31 9:05:50

使用场景

后端可能存在SQL注入的漏洞，但是对参数有一些过滤。
当我们不确定过滤了什么符号、函数时，可以使用FUZZ字典。
通过对比响应的结果的区别，我们就能知道什么关键字有过滤，什么关键字没有，然后可以使用没有过滤的关键字进行注入。

思路就是找不一样的响应结果。

使用方法

使用Burp Suite抓包，发送到Intruder模块。
标记有可能有注入漏洞的字段。
字典选择以上内容，可以粘贴，也可以从文件读取。
发送攻击，查看响应长度，再查看具体响应内容。
如果所有的响应长度都一样，说明有可能没有注入漏洞，或者全部都被过滤了。
如果响应长度分为几种，那么可以看看响应内容的区别。
