漏洞描述

E-Cology OA协同商务系统是一款面向中大型组织的数字化办公产品，它基于全新的设计理念和管理思想，旨在为中大型组织创建一个全新的高效协同办公环境。其WorkflowServiceXml接口存在sql注入，恶意攻击者可能会向数据库发送构造的恶意SQL查询语句，以获取数据库敏感信息、修改数据或者执行其他恶意操作，还有可能直接通过sql注入获取服务器权限。

漏洞复现

1）信息收集
fofa：app="泛微-OA（e-cology）"
hunter：app.name="泛微 e-cology OA"

当时共我赏花人，点检如今无一半。

2）构造数据包

POST /services/WorkflowServiceXml HTTP/1.1
