CVE-2018-0983 is a local elevation of privilege vulnerability in Windows Storage Services affecting Windows 10 versions 1511, 1607, 1703, and 1709, Windows Server 2016, and Windows Server version 1709. The flaw is in the StorSvc RPC method SvcMoveFileInheritSecurity, which handles file moves and then reapplies inherited security on the destination object. In the vulnerable logic, the service impersonates the caller to move a file, then reverts to SYSTEM and resets the destination file's security descriptor. By supplying a hardlinked file and leveraging directory permissions that allow the move to succeed, an unprivileged user can cause the service to apply inherited access control entries to an arbitrary target file while running as SYSTEM. This results in attacker-controlled modification of the target file's security descriptor and enables privilege escalation.
