Pagekit CMS 1.0.18 的系统更新下载接口 /admin/system/update/download 中存在服务端请求伪造（SSRF）漏洞。
该接口接受用户通过 POST 参数传入的 url 值，未对 URL 的协议（scheme）、目标主机（host）进行任何验证或白名单限制，直接将其传入 PHP 的 fopen() 函数执行文件读取/网络请求，并将获取到的内容写入服务器临时目录。
攻击者（需具备管理员权限）可利用此漏洞：
1. 通过 file:// 协议读取服务器本地任意文件
2. 探测内网端口和服务
3. 访问云实例元数据（如 http://x.x.x.x/）窃取云凭据
4. 向内网服务发起攻击请求
A Server-Side Request Forgery (SSRF) vulnerability exists in the system update download endpoint of Pagekit CMS 1.0.18.
The POST /admin/system/update/download endpoint accepts a user-supplied url parameter and passes it directly to PHP's fopen() function without any validation on the URL scheme, target host, or content. The fetched content is then written to a temporary file on the server via file_put_contents().
An authenticated administrator can exploit this vulnerability to:
1. Read arbitrary local files on the server via the file:// protocol
2. Scan internal network ports and services
3. Access cloud instance metadata (e.g., http://x.x.x.x/) to steal cloud credentials
4. Send requests to internal network services as a pivot point |
