该扩展提供了一个公共代理端点，可代表访客获取指定 URL。对于其中一种 HTTP 请求方法，该端点未应用用于保护其他方法的身份验证检查，因此其获取的 URL 完全由请求者控制。未认证的攻击者可利用此漏洞，使服务器向任意内部或外部主机发起请求。攻击者能够获取响应状态码及部分响应头信息，从而探测内部主机和端口；但响应正文不会被披露。

Vulnerability Title
Server-Side Request Forgery in extension "Kitodo.Presentation" (dlf)
Source: CVE Program / CVE List V5
Vulnerability Description
The extension provides a public proxy endpoint that fetches a URL on behalf of the visitor. For one HTTP request method, the endpoint does not apply the authorization check that protects the other methods, so the URL it fetches is fully controlled by the requester. An unauthenticated attacker can make the server send requests to arbitrary internal or external hosts. The attacker receives the status code and selected response headers, which allows probing of internal hosts and ports. Response bodies are not disclosed.
