# PHP-FPM FastCGI 未授权访问漏洞
|
||||
|
||||
PHP-FPM(FastCGI 进程管理器)是一个替代性的 PHP FastCGI 实现,为各种规模的网站提供了额外的功能特性,特别适用于高负载网站。当配置不当时,PHP-FPM 可能被直接通过 FastCGI 协议访问,允许攻击者执行任意 PHP 代码。
|
||||
|
||||
此漏洞发生在 PHP-FPM 在没有适当访问控制的情况下暴露在网络中,导致 FastCGI 接口可被未经授权访问。
|
||||

||||

|
||||
|
||||
## 环境搭建
|
||||
|
||||
执行如下命令启动PHP-FPM服务器:
|
||||
|
||||
```bash
|
||||
docker compose up -d
|
||||
```
|
||||
|
||||
服务启动后,PHP-FPM 服务器将监听 9000 端口。
|
||||
|
||||
## 漏洞复现
|
||||
|
||||
漏洞利用脚本可在以下地址获取:https://gist.github.com/phith0n/9615e2420f31048f7e30f3937356cf75
|
||||
|
||||
该脚本允许你:
|
||||
|
||||
1. 直接连接到 PHP-FPM 端口
|
||||
2. 发送精心构造的 FastCGI 请求
|
||||
3. 在目标服务器上执行任意 PHP 代码
|
||||
|
||||
成功利用结果:
