CVE-2023-32347Network attack vector

Root command execution via device identity impersonation

Published May 22, 2023 · Updated Jan 16, 2025

Improper authentication in Teltonika Networks Remote Management System before 4.10.0 allows remote attackers to execute commands as root. Device claiming and device authentication treat a serial number and MAC address as sufficient identity, allowing a matching pair to impersonate the device and obtain its communication credentials. Knowledge of both identifiers is required; the impersonated registration then exposes management functions that execute arbitrary commands on the device.
