'Allow Basic authentication' (WinRM Service)ID: oval:org.secpod.oval:def:40315 | Date: (C)2017-04-25 (M)2023-07-04 |
Class: COMPLIANCE | Family: windows |
This policy setting allows you to manage whether the Windows Remote Management (WinRM) service accepts Basic authentication from a remote client.
If you enable this policy setting, the WinRM service will accept Basic authentication from a remote client.
If you disable or do not configure this policy setting, the WinRM service will not accept Basic authentication from a remote client.
Vulnerability:
Basic authentication is less robust than other authentication methods available in WinRM because credentials including passwords are transmitted in plain text. An attacker who is able to capture packets on the network where WinRM is running may be able to determine the credentials used for accessing remote hosts via WinRM.
Counter Measure:
Disable this policy setting.
Potential Impact:
If you enable this policy setting, the WinRM service will accept Basic authentication from a remote client.
If you disable or do not configure this policy setting, the WinRM service will not accept Basic authentication from a remote client.
Fix:
(1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Remote Management (WinRM)\WinRM Service\Allow Basic authentication
(2) REG: HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WinRM\Service!AllowBasic
