## Overview

The authentication framework used by affected Kiloview E3 NDI encoder firmware signs session JSON Web Tokens using an HMAC-SHA256 secret hardcoded as a static string within the firmware image, identical across all deployed devices. An attacker with access to the publicly distributed firmware can recover this secret and forge arbitrary session tokens, including administrative tokens, without valid credentials, enabling unauthenticated access to privileged device functions.

## Affected

- `e3_firmware < 1.30`

## Remediation

KiloView recommends users update to V1.30:  https://www.kiloview.com/en/download/e3-firmware-downloadlatest-12/
