CVE-2021-21590
Dell EMC Unity, Unity XT, and UnityVSA versions prior to 5.1.0.0.5.394 contain a plain-text password storage vulnerability.
Does this matter?
Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.

Dell EMC Unity, Unity XT, and UnityVSA versions prior to 5.1.0.0.5.394 contain a plain-text password storage vulnerability. A local malicious user with high privileges may use the exposed password to gain access with the privileges of the compromised user.
