Microsoft network client: Send unencrypted password to third-party SMB serversID: oval:org.secpod.oval:def:34987 | Date: (C)2016-06-10 (M)2023-12-13 |
Class: COMPLIANCE | Family: windows |
If this security setting is enabled, the Server Message Block (SMB) redirector is allowed to send plaintext passwords to non-Microsoft SMB servers that do not support password encryption during authentication.
Sending unencrypted passwords is a security risk.
Default: Disabled
Counter Measure:
Configure the Microsoft network client: Send unencrypted password to connect to third-party SMB servers setting to Disabled.
Potential Impact:
Some very old applications and operating systems such as MS-DOS, Windows for Workgroups 3.11, and Windows 95a may not be able to communicate with the servers in your organization by means of the SMB protocol.
Fix:
(1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Microsoft network client: Send unencrypted password to third-party SMB servers
(2) REG: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanWorkstation\Parameters!EnablePlainTextPassword
