CVE-2020-5319
Dell EMC Unity, Dell EMC Unity XT, and Dell EMC UnityVSA versions prior to 5.0.2.0.5.009 contain a Denial of Service vulnerability on NAS Server SSH implementation that is used to provide SFTP service on a NAS server.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.40%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
