    else:

在dos窗口执行以下命令,即可获得cookie,如果是v11版本则将下面命令里面的2017换成11。

python oa_poc.py -v 2017 -url http://通达oa的web登录地址

二、替换浏览器cookie

在浏览器中打开http://通达OA的web地址/general/index.php 这时会提示没有登录,直接F12,找到存储cookie,将PHPSESSID的值修改为python脚本结果里面的值。

替换完成后刷新页面即可看到以管理员身份登录成功!

总结:

建议所有的业务系统一定要跟官网保持同步升级,要么就是完全的使用内网访问(当然这只能一定程度上防范外部人员)。还有就是定期去关注一些网络公司发布的公告!

如果是自研系统,在系统设计环节重要的功能有必要二次验证当前用户的登录密码,以及使用其他二次校验密码!另外系统增加一定的风险预警也是有必要的比如在非业务时间或ip发生了用户登录或操作事件及时触发报警通知。
