SYSTEM code execution via installer-created folder permissions
Published Apr 10, 2026 · Updated Apr 10, 2026
Privilege escalation in Samsung Electronics MagicINFO 9 Server before 21.1091.1 allows local users to gain SYSTEM access via folder permissions. The product installer creates a folder with default permissions that let low-privileged code modify content later used in the SYSTEM context. Exploitation requires existing low-privileged code execution on the Windows server and grants arbitrary code execution as SYSTEM.
