Vulnerability discussion

This check verifies that Windows elevates all applications, not just signed ones.

Check content

Analyze the system using the Security Configuration and Analysis snap-in. Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -> Security Options. If the value for “User Account Control: Only elevate executables that are signed and validated” is not set to “Disabled”, then this is a finding. The policy referenced configures the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Microsoft\Windows\CurrentVersion\Policies\System\ Value Name: ValidateAdminCodeSignatures Value Type: REG_DWORD Value: 0

Fix text

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> “User Account Control: Only elevate executables that are signed and validated” to “Disabled”.

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.
