SecuriTricks - CVE-2026-28742

Description

Naxclow devices use a uniform request-signing scheme based on a hard-coded, platform-wide salt embedded in every firmware image. Once this salt is recovered from any device, an attacker can generate valid signatures for arbitrary device or account operations due to the absence of per-device keys, server-side nonce tracking, or replay protections. Combined with the system’s use of plain HTTP for control-plane traffic, the construction enables broad request forgery and impersonation across the platform.
