MediaFlow Proxy through 2.4.9 contains a server-side request forgery vulnerability in the /proxy routes due to missing and incomplete destination validation in the d query parameter. Remote attackers can supply arbitrary internal URLs including loopback and cloud metadata endpoints to read full responses from the proxy server.
Weakness
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
