Windows SeManageVolumePrivilege Can Enable SYSTEM Escalation Through ACL Changes and DLL Hijacking
Summary
A Windows 10 walkthrough shows how attackers can abuse a misassigned SeManageVolumePrivilege to change C:\Windows permissions and escalate privileges through DLL hijacking. It also outlines monitoring and mitigation measures.
Key points
- The walkthrough demonstrates abuse of SeManageVolumePrivilege, the Windows “Perform volume maintenance tasks” right, when assigned to a standard user.
- After enabling the token privilege, an attacker can use SeManageVolumeExploit to change ACLs across C:\Windows, granting BUILTIN\Users write access.
- The article shows Print Spooler DLL hijacking and Windows Error Reporting abuse to obtain SYSTEM-level access.
- A separate WBEM DLL hijacking path obtains a NETWORK SERVICE shell, which the article describes as a stepping stone to SYSTEM.
- Restrict the right to administrators or explicitly required service accounts, and audit user-right assignments for unintended grants.
- Monitor token privilege activation and protected-directory ACL changes; the article cites Windows Event IDs 4703 and 4670.
- The article recommends DLL-loading controls, hardening or disabling unnecessary Print Spooler and WER exposure, and EDR monitoring.
