CVE-2025-0065

SYSTEM code execution via service argument injection

Published Jan 28, 2025 · Updated Jan 28, 2025

Argument injection in TeamViewer Full Client and Host for Windows allows local users to execute arbitrary code with SYSTEM privileges. TeamViewer_service.exe passes a user-supplied string to a system call without validating argument delimiters, so injected arguments change privileged execution. Exploitation requires the ability to run low-privileged code locally, and successful use grants arbitrary code execution as SYSTEM.
