# Laravel .env 配置文件泄露 CVE-2017-16894
|
||
|
|
|
||
|
|
## 漏洞描述
|
||
|
|
|
||
|
|
Laravel Framework 是 Taylor Otwell 软件开发者开发的一款基于 PHP 的 Web 应用程序开发框架。 Laravel framework 5.5.21 及之前的版本中存在 .env 文件可被下载的信息泄露漏洞。远程攻击者可利用该漏洞获取敏感信息
|
||
|
|
|
||
|
|
## 漏洞影响
|
||
|
|
|
||
|
|
```
|
||
|
|
Laravel framework <= 5.5.21
|
||
|
|
```
|
||
|
|
|
||
|
|
## 网络测绘
|
||
|
|
|
||
|
|
```
|
||
|
|
app="Laravel-Framework"
|
||
|
|
```
|
||
|
|
|
||
|
|
## 漏洞复现
|
||
|
|
|
||
|
|
访问目标 url http://xxx.xxx.xxx.xxx/.env
|
||
|
|
|
||
|
|
当配置不当且在影响范围内时会出现 **.env 可被下载的情况**，导致数据库账号密码等敏感信息的泄露
|
||
|
|
|
||
|
|
这里使用 POC 脚本来进行信息获取
