Title

Windows Server 2022 create symbolic links user right must only be assigned to the Administrators group.

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 other than the following are granted the "Create symbolic links" user right, this is a finding: - Administrators 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 other than the following are granted the "SeCreateSymbolicLinkPrivilege" user right, this is a finding: S-1-5-32-544 (Administrators) Systems that have the Hyper-V role will also have "Virtual Machines" given this user right (this may be displayed as "NT Virtual Machine\Virtual Machines", SID S-1-5-83-0). This is not a finding.

Discussion

Inappropriate granting of user rights can provide system, administrative, and other high-level capabilities. Accounts with the "Create symbolic links" user right can create pointers to other objects, which could expose the system to attack.
