CVE-2018-5495
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAll StorageGRID Webscale versions are susceptible to a vulnerability which could permit an unauthenticated attacker to communicate with systems on the same network as the StorageGRID Webscale Admin Node via HTTP or to take over services on the Admin Node.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is an HTTP routing/proxy vulnerability in StorageGRID Webscale Admin Node that allows an unauthenticated attacker to send HTTP requests to internal systems on the same network (similar to SSRF) or potentially take over services running on the Admin Node itself, requiring no authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if NetApp StorageGRID Webscale Admin Node is installedCheck your environment for the presence of StorageGRID Webscale Admin Node software - look for StorageGRID processes, services, or management interfaces on the systemAffected if StorageGRID Webscale Admin Node is present on the network or as a service
-
Determine if the Admin Node is network-accessibleReview firewall rules and network access controls to determine if the Admin Node management interface (typically ports 443, 80) is exposed to untrusted or external networksAffected if The Admin Node HTTP/HTTPS ports are reachable from untrusted networks without proper filtering
-
Check for unauthenticated HTTP proxy functionalityTest if the Admin Node allows HTTP requests to internal resources by attempting to access internal IPs or localhost through the Admin Node's HTTP interface (e.g., curl or similar tool sending requests to internal endpoints)Affected if The Admin Node proxies requests to internal systems without requiring authentication
-
Verify network segmentation of Admin NodeReview network topology to confirm the Admin Node is not directly accessible from outside the trusted network segment and that internal systems are properly isolatedAffected if Admin Node has direct access to internal network segments without firewall protection
If NetApp StorageGRID Webscale Admin Node is present and its management interface is accessible from untrusted networks, the environment is vulnerable to this unauthenticated SSRF attack.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict network access to the Admin Node, implement proper firewall rules to limit HTTP/HTTPS exposure, and apply vendor-provided patches or configuration changes to disable unauthenticated HTTP proxy functionality.
