An arbitrary file write 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 which allows remote code execution. 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-2020-8982.
