An SSRF issue was discovered in OpenStack Glance before Newton. The \'copy_from\' feature in the Image Service API v1 allowed an attacker to perform masked network port scans. With v1, it is possible to create images with a URL such as \'http://localhost:22\'. This could then allow an attacker to enumerate internal network details while appearing masked, since the scan would appear to originate from the Glance Image service.
