Vulnerability Discussion
The lack of password protection enables anyone to gain access to the information system, which opens a backdoor opportunity for intruders to compromise the system as well as other resources. Accounts on a system must require passwords.
Check
Review the password required status for enabled user accounts.
Open "PowerShell".
Domain Controllers:
Enter "Get-Aduser -Filter * -Properties Passwordnotrequired |FT Name, Passwordnotrequired, Enabled".
Exclude disabled accounts (e.g., DefaultAccount, Guest) and Trusted Domain Objects (TDOs).
If "Passwordnotrequired" is "True" or blank for any enabled user account, this is a finding.
Member servers and standalone or nondomain-joined systems:
Enter 'Get-CimInstance -Class Win32_Useraccount -Filter "PasswordRequired=False and LocalAccount=True" | FT Name, PasswordRequired, Disabled, LocalAccount'.
Exclude disabled accounts (e.g., DefaultAccount, Guest).
If any enabled user accounts are returned with a "PasswordRequired" status of "False", this is a finding.
Fix
Configure all enabled user accounts to require passwords.
The password required flag can be set by entering the following on a command line: "Net user [username] /passwordreq:yes", substituting [username] with the name of the user account.
