## Description

NeuVector 3.1 when configured to allow authentication via Active Directory, does not enforce non-empty passwords which allows an attacker with access to the Neuvector portal to authenticate as any valid LDAP user by providing a valid username and an empty password (provided that the active directory server has not been configured to reject empty passwords).

## What to do
