The copy function in application/admin/controller/Article.php in NoneCms 1.3.0 allows remote attackers to access the content of internal and external network resources via Server Side Request Forgery (SSRF), because URL validation only considers whether the URL contains the csdn substring.
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.
