A server-side request forgery vulnerability exists in the cecho.php functionality of MedDream PACS Premium 7.3.5.860. A specially crafted HTTP request can lead to SSRF. An attacker can make an unauthenticated HTTP request to trigger this vulnerability.
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.
