CVE-2024-7479

Privilege escalation via unverified VPN driver installation

Published Sep 25, 2024 · Updated Sep 25, 2024

Improper signature verification in TeamViewer Remote clients before 15.58.4 allows local users to install drivers with elevated privileges. The TeamViewer_service.exe service exposes driver-installation functionality on TCP port 5939 without authenticating callers and improperly verifies the VPN driver's signature. Low-privileged local code execution is required, after which arbitrary code can run as SYSTEM.
