Official description

Dell PowerScale OneFS versions 8.2.0.x through 9.3.0.x, contain a weak password requirement vulnerability. An administrator may create an account with no password. A remote attacker may potentially exploit this leading to a user account compromise.

The underlying weakness: Weak Password Requirements

The product does not require that users should have strong passwords.

How developers prevent this class of flaw

  • Consider a second authentication factor beyond the password, which prevents the password from being a single point of failure. See CWE-308 for further information.
  • Consider implementing a password complexity meter to inform users when a chosen password meets the required attributes.
