Vulnerability discussion

A compromised local administrator account can provide means for an attacker to move laterally between domain systems. With User Account Control enabled, filtering the privileged token for local administrator accounts will prevent the elevated privileges of these accounts from being used over the network.

Check content

If the system is not a member of a domain, this is NA. If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\ Value Name: LocalAccountTokenFilterPolicy Type: REG_DWORD Value: 0 This setting may cause issues with some network scanning tools if local administrative accounts are used remotely. Scans should use domain accounts where possible. If a local administrative account must be used, temporarily enabling the privileged token by configuring the registry value to 1 may be required.

Fix text

Configure the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\ Value Name: LocalAccountTokenFilterPolicy Type: REG_DWORD Value: 0

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
