测试了一下可以新建，删除文件：
新建一个文件:upload_bak2.jsp
touch /www/projects/hssms/upload/upload_bak2.jsp
====================================================================================================================================
查看文件：
ls /www/projects/hssms/upload/
====================================================================================================================================
error.jsp
success.jsp
upload_bak2.jsp
upload_bak.jsp
upload.jsp
打开新建的，文件内容是空的：
cat /www/projects/hssms/upload/upload_bak2.jsp
====================================================================================================================================
删除新建测试文件：upload_bak2.jsp
rm /www/projects/hssms/upload/upload_bak2.jsp
====================================================================================================================================
测试文件被删除了：
ls /www/projects/hssms/upload/
====================================================================================================================================
/www/projects/hssms/upload/:

success.jsp
upload_bak.jsp
upload.jsp
这里可以发现，如果被人利用这个漏洞可以删除整个站点的文件！

看到了Oracle数据库的连接用户名和密码：
于是连接上数据库：

管理员和用户的登录账号信息：

dw2.png


这里因该是设置了不许外网登录吧，看里面的登录日志都是内网Ip的。
到此这个平台的整站文件，数据库数据都可以被利用任意操作！！

修复方案：

1. 参照官方说明升级struts2版本
2. 数据库加强安全策略，不允许外网联接，或者指定的Ip才能外联数据库。
