CVE-2021-28499
In Arista's MOS (Metamako Operating System) software which is supported on the 7130 product line, user account passwords set in clear text could leak to users without any password.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
