CVE-2026-92450— Kiloview E3 NDI Encoder Use of Hard-coded Credentials

Quick assessment

Affected
Kiloview E3 Firmware
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

受影响的 Kiloview E3 NDI 编码器固件所使用的认证框架，使用硬编码在固件镜像中的静态字符串作为 HMAC-SHA256 密钥来对会话 JSON Web Token（JWT）进行签名，且该密钥在所有部署的设备中完全相同。任何能够获取公开分发的固件的攻击者均可提取该密钥，并伪造任意会话令牌（包括管理员令牌），而无需提供有效凭据，从而实现对设备特权功能的未授权访问。

Vulnerability Title
Kiloview E3 NDI Encoder Use of Hard-coded Credentials
Source: CVE Program / CVE List V5
Vulnerability Description
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.
