CVE-2025-54857Network attack vector

Unauthenticated root command execution via Web UI

Published Sep 1, 2025 · Updated Sep 2, 2025

OS command injection in Seiko Solutions SkyBridge BASIC MB-A130 1.5.8 and earlier allows remote attackers to execute commands as root. The Web UI permits command execution without login authentication, but the vendor does not disclose the affected endpoint or how input reaches an OS command. Exploitation requires network access to the Web UI; WAN access is disabled and LAN access is enabled in the factory configuration, and successful commands have full root privileges.
