CVE-2026-82104 · Severity: info · Published 2026-10-30

Teltonika Networks industrial routers and switches running RUTOS and TSWOS firmware contain a critical authentication bypass that allows unauthenticated attackers to execute arbitrary OS commands. An attacker can directly invoke Lua functions that normally require authentication, bypassing security validations and gaining full control of the device. This could compromise network infrastructure and enable lateral movement into critical business systems.

## Technical details

An unauthenticated remote attacker can directly call Lua functions in the device's API without following the normal request validation flows, allowing bypass of authentication and authorization checks. By calling Lua functions directly, an attacker gains the ability to execute arbitrary OS commands with the privileges of the application. The vulnerability affects RUTOS versions 7.22–7.24.2 across multiple device models and TSWOS versions 1.9–1.10.

## Affected products

- Teltonika Networks RUTOS 7.22 through 7.24.2
- Teltonika Networks TSWOS 1.9 through 1.10
