Teltonika RUT devices allow unauthenticated command execution

CVE-2026-82104 · published 10 days ago
Summary

Several Teltonika Networks router models (RUT, RUTX, RUTM, RUTC, ATRM and related firmware versions) let anyone call internal functions without logging in, which can lead to the system running arbitrary commands. This bypasses normal checks and could let an attacker take control of the device. Update the firmware to the latest version or apply the vendor’s security patch as soon as possible.

Original advisory text
API permission bypass via logic bug
In Teltonika Networks RUTOS devices running versions from 7.22 through 7.24.2 and TSWOS devices running versions 1.9 through 1.10, a vulnerability exists whereby an unauthenticated user can directly call LUA functions, bypassing validations that might be called under normal API requests. Due to those requests not following proper flows, this could lead to OS command execution.
