Vulnerability discussion

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities.Accounts with the "Act as part of the operating system" user right can assume the identity of any user and gain access to resources that user is authorized to access. Any accounts with this right can take complete control of a system.

Check content

Verify the effective setting in Local Group Policy Editor. Run "gpedit.msc". Navigate to Local Computer Policy >> Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> User Rights Assignment. If any accounts or groups (to include administrators), are granted the "Act as part of the operating system" user right, this is a finding. If an application requires this user right, this would not be a finding. Vendor documentation must support the requirement for having the user right. The requirement must be documented with the ISSO. The application account must meet requirements for application account passwords, such as length (WN12-00-000010) and required frequency of changes (WN12-00-000011).

Fix text

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> User Rights Assignment >> "Act as part of the operating system" to be defined but containing no entries (blank).

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.
