Vulnerability discussion

The registry is integral to the function, security, and stability of the Windows system. Some processes may require anonymous access to the registry. This must be limited to properly protect the system.

Check content

Run "Regedit". Navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers\winreg\ If the key does not exist, this is a finding. Right-click on "winreg" and select "Permissions…". Select "Advanced". If the permissions are not as restrictive as the defaults listed below, this is a finding. The following are the same for each permission listed: Type - Allow Inherited from - Columns: Name - Permission - Apply to Administrators - Full Control - This key and subkeys Backup Operators - Special - This key only (Special = Query Value, Enumerate Subkeys, Notify, Read Control (effectively = Read)) LOCAL SERVICE - Read - This key and subkeys

Fix text

Maintain permissions at least as restrictive as the defaults listed below for the "winreg" registry key. It is recommended to not change the permissions from the defaults. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers\winreg\ The following are the same for each permission listed: Type - Allow Inherited from - Columns: Name - Permission - Apply to Administrators - Full Control - This key and subkeys Backup Operators - Special - This key only (Special = Query Value, Enumerate Subkeys, Notify, Read Control (effectively = Read)) LOCAL SERVICE - Read - This key and subkeys

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.
