Submit #750708: cskefu v8 Server-Side Request Forgeryinfo

Titlecskefu v8 Server-Side Request Forgery
DescriptionA vulnerability has been found in cskefu v8. This vulnerability affects the function url of the file com/cskefu/cc/controller/resource/MediaController.java. The manipulation of the argument url with the input pointing to internal network resources leads to server-side request forgery (SSRF). The application exposes an endpoint /res/url which takes a user-controlled URL. While there is a regular expression check (^https?://.*/.*$), it only validates the protocol and the presence of a path, but fails to restrict requests to the local loopback interface or internal network segments. This allows remote attackers to scan internal ports, access internal service metadata
