CVE-2017-7200
Description
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).
Statement
Because the Image Service APIv1 was deprecated in Newton and because a workaround is possible, no fix is being made available.

Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
