JizhiCMS v2.5.4 was discovered to contain a Server-Side Request Forgery (SSRF) via the component cPluginsController.php. This vulnerability allows attackers to perform an intranet scan via a crafted request.
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.
