Ensure 'Allow VBA to load typelib references by path from untrusted intranet locations' is set to 'Disabled'

YüksekDüzey 1Otomatikoffice

Açıklama

This policy setting permits VBA to load typelib references by explicit path read from the project data if that path points to an intranet location that is not explicitly in the system trusted sites list. Rationale: The Visual Basic Application language can be abused by manipulating typelib references stored in untrusted locations. By preventing a user from overriding the default security settings this prevents a change to an unsecure state where harmful software could be more easily executed on a system. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\vba\security:allowvbaintranetreferences (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 0. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.
