Vulnerability discussion

The registry is integral to the function, security, and stability of the Windows system. Some processes may require remote access to the registry. This setting controls which registry paths and sub-paths are accessible from a remote computer. These registry paths must be limited, as they could give unauthorized individuals access to the registry.

Check content

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: \System\CurrentControlSet\Control\SecurePipeServers\Winreg\AllowedPaths\ Value Name: Machine Value Type: REG_MULTI_SZ Value: see below Software\Microsoft\OLAP Server Software\Microsoft\Windows NT\CurrentVersion\Perflib Software\Microsoft\Windows NT\CurrentVersion\Print Software\Microsoft\Windows NT\CurrentVersion\Windows System\CurrentControlSet\Control\ContentIndex System\CurrentControlSet\Control\Print\Printers System\CurrentControlSet\Control\Terminal Server System\CurrentControlSet\Control\Terminal Server\UserConfig System\CurrentControlSet\Control\Terminal Server\DefaultUserConfiguration System\CurrentControlSet\Services\Eventlog System\CurrentControlSet\Services\Sysmonlog Legitimate applications may add entries to this registry value. If an application requires these entries to function properly and is documented with the ISSO, this would not be a finding. Documentation must contain supporting information from the vendor's instructions.

Fix text

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> "Network access: Remotely accessible registry paths and sub-paths" with the following entries: Software\Microsoft\OLAP Server Software\Microsoft\Windows NT\CurrentVersion\Perflib Software\Microsoft\Windows NT\CurrentVersion\Print Software\Microsoft\Windows NT\CurrentVersion\Windows System\CurrentControlSet\Control\ContentIndex System\CurrentControlSet\Control\Print\Printers System\CurrentControlSet\Control\Terminal Server System\CurrentControlSet\Control\Terminal Server\UserConfig System\CurrentControlSet\Control\Terminal Server\DefaultUserConfiguration System\CurrentControlSet\Services\Eventlog System\CurrentControlSet\Services\Sysmonlog

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.
