CVE-2017-7200

The copy_from feature in Image Service API v1 allows an attacker to perform masked network port scans. It is possible to create images with a URL such as ‘http://localhost:22’. This could allow an attacker to enumerate internal network details while appearing masked, because the scan appears to originate from the Image Service. This is classified as a Server-Side Request Forgery (SSRF). Note: Some knowledge of the internal network might be necessary to exploit this flaw internally (apart from localhost).
