CVE-2020-8982
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 · uneditedAn unauthenticated arbitrary file read issue exists in all versions of Citrix ShareFile StorageZones (aka storage zones) Controller, including the most recent 5.10.x releases as of May 2020. RCE and file access is granted to everything hosted by ShareFile, be it on-premise or inside Citrix Cloud itself (both are internet facing). NOTE: unlike most CVEs, exploitability depends on the product version that was in use when a particular setup step was performed, NOT the product version that is in use during a current assessment of a CVE consumer's product inventory. Specifically, the vulnerability can be exploited if a storage zone was created by one of these product versions: 5.9.0, 5.8.0, 5.7.0, 5.6.0, 5.5.0, or earlier. This CVE differs from CVE-2020-7473 and CVE-2020-8983.
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 confidenceUnauthenticated arbitrary file read vulnerability in Citrix ShareFile StorageZones Controller allowing access to all hosted files. The critical nuance is that exploitability depends on the product version used WHEN the storage zone was originally created (5.9.0, 5.8.0, 5.7.0, 5.6.0, 5.5.0, or earlier), not the currently deployed version—even systems now running 5.10.x remain vulnerable if created with affected versions.

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.
-
Check current StorageZones Controller versionOpen Windows Programs and Features, find 'Citrix ShareFile StorageZones Controller' and note the version, or log into the StorageZones Controller admin interface and check the About pageAffected if Current version is <= 5.5.0, 5.6.0, 5.7.0, 5.8.0, or 5.9.0
-
Identify original zone creation versionLocate the StorageZones Controller configuration database or XML configuration files that store zone metadata. Query or inspect for the 'CreationVersion' or similar field that records which product version was used when the StorageZone was initially createdAffected if The stored creation version is <= 5.5.0, 5.6.0, 5.7.0, 5.8.0, or 5.9.0, regardless of current version (including 5.10.x)
-
Verify StorageZones Controller network exposureReview firewall rules and IIS site bindings to determine if the StorageZones Controller web interface is accessible from untrusted networks or the internet without authenticationAffected if The controller is exposed to unauthenticated network access from internet or untrusted LAN segments
You are affected if your StorageZone was originally created with version 5.9.0 or earlier (including 5.5.0, 5.6.0, 5.7.0, 5.8.0), even if currently running 5.10.x or later, and the interface is network-accessible to unauthenticated users.

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 dataIdentify the product version originally used when each StorageZone was created; recreate StorageZones using a patched version (5.11.0+) or apply vendor-supplied remediation for zones created with vulnerable versions.
