CVE-2025-64992Network attack vector

Elevated command execution via unvalidated instruction input

Published Dec 11, 2025 · Updated Dec 11, 2025

Command injection in TeamViewer DEX before instruction version 25 allows remote authenticated users to execute elevated commands. The 1E-Nomad-PauseNomadJobQueue instruction fails to validate attacker-controlled input before using it for command execution. Exploitation requires Actioner privileges and approval by a separate highly privileged user, after which commands run elevated on connected devices.
