Control

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 are granted the "Access Credential Manager as a trusted caller" user right, this is a finding. For server core installations, run the following command: Secedit /Export /Areas User_Rights /cfg c:\path\filename.txt Review the text file. If any SIDs are granted the "SeTrustedCredManAccessPrivilege" user right, this is a finding.

Discussion

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. Accounts with the "Access Credential Manager as a trusted caller" user right may be able to retrieve the credentials of other accounts from Credential Manager.
