What is CVE-2020-7473?

CVE-2020-7473 is a high-severity path traversal vulnerability in n/a, published on 7 May 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

In certain situations, all versions of Citrix ShareFile StorageZones (aka storage zones) Controller, including the most recent 5.10.x releases as of May 2020, allow unauthenticated attackers to access the documents and folders of ShareFile users. 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-2020-8982 and CVE-2020-8983 but has essentially the same risk.
