CVE-2025-64988Network attack vector

Authenticated command execution via unvalidated instruction input

Published Dec 11, 2025 · Updated Dec 11, 2025

Command injection in TeamViewer DEX before 19.2 allows remote authenticated users to execute elevated commands on connected devices. The 1E-Nomad-GetCmContentLocations instruction fails to validate attacker-controlled input before incorporating it into commands. Actioner privileges are required, but the non-interactive instruction needs no second-user approval and runs injected commands with elevated rights on managed endpoints.
